MAXIM INTEGRATED PRODUCTS MAX1473EUI+ IF RECEIVER, 300MHZ-450MHZ, TSSOP-28The MAX1473EUI+ is a 315MHz 433MHz ASK superheterodyne receiver with extended dynamic range in 28 pin TSSOP package. This fully integrated low power CMOS receiver is ideal for receiving amplitude shift keyed (ASK) data in the 300MHz to 450MHz frequency range. Its signal range is from 114dBm to 0dBm. With few external components and a low current power down mode it is ideal for cost and power sensitive applications typical in automotive and consumer
The MAX1473EUI+ is a 315MHz/433MHz ASK superheterodyne receiver with extended dynamic range in 28 pin TSSOP package. This fully integrated low power CMOS receiver is ideal for receiving amplitude shift-keyed (ASK) data in the 300MHz to 450MHz frequency range. Its signal range is from -114dBm to 0dBm. With few external components and a low current power down mode it is ideal for cost and power sensitive applications typical in automotive and consumer markets. The chip consists of a low noise amplifier LNA , a fully differential image rejection mixer, an on-chip phase locked loop with integrated voltage controlled oscillator, a 10.7MHz IF limiting amplifier stage with received signal strength indicator and analogue baseband data recovery circuitry. It also has a discrete one step automatic gain control that drops the LNA gain by 35dB when the RF input signal is greater than -57dBm. It is used in automotive remote keyless entry, garage door openers, remote controls & home automation.

Loved
Format: Kindle
This story had me hooked from just the first few chapters. I literally could not put it down, I love a good forbidden love story and this was just *chefs kiss*.
I could feel the chemistry between Ana and Rachel from the moment they met. Their conversations are so well written, I loved the banter between them both. The drama throughout the book had me saying "just one more chapter before I take a break". I appreciated that you can tell that the author was knowledgeable about both of the main characters profession and religion and that the book took a focus on recognizing the characters differences and showing Ana take the time to learn about Rachel's religion. That was such a great touch that I loved.
The only reason that I gave this book 4 stars instead of 5 is that the resolution of the drama and story seemed a bit anticlimactic. There was all this tension from secrets kept that once they came out both characters seemed to move on and get their happily ever after.
Overall, I loved this book and its characters. I definitely will be picking up any book that this author puts out!

Amazing read!
Format: Kindle
I loved this book so much! I might be a little biased because I loved the first one so much and I’ve been dying for Ana to get happy ending ever since, but it was definitely a good book all around.
Ana and Rachel were absolutely perfect for each other. They have the kind of opposing personalities that fit together like a puzzle. Where Rachel was a little more reserved and polished, Ana was more outgoing and messy. They didn’t clash, they completed each other. I’m not going to lie, love that they’re a doctor and a lawyer because they’re giving sapphic power couple.
I also loved all of the supportive family members and best friends in this book. Stella and Charlotte were super cute and I hope we get to see them again in a later book.
I thoroughly enjoyed this book and I’d recommend it to anyone looking for an opposites attract, doctor/lawyer romance. This is the second book that I’ve read from Morgan and it seems like she doesn’t miss.

Sapphic Lawyer and Doctor
Format: Paperback
I loved this book… which is why I was very disappointed when the conflict was “solved” so easily and lowkey brushed past. We are waiting for this secret to come out that Rachel has been holding onto. There’s obviously conflict of interest with Ana and Rachel. But the way they solved it? I didn’t feel like it was realistic and it felt like both women were like, “Okay, that’s over, everything is kosher now(pun intended?). It honestly prevented me from giving it 5 stars. The ending seems so rushed.
But other than that, I loved both characters! I loved learning about Jewish culture and loved how the author portrayed it. Both MCs are fleshed out, in depth characters. The author had a good balance of humor

Enjoyable Doctor, Lawyer Romance
Format: Paperback
A very enjoyable and engaging story. The medical and legal aspects of this story was very fascinating. I never get tired of reading romances that are about those troupes. The romance between the main characters was very sweet with not A lot of drama or angst. Sometimes I prefer A story with less drama and angst. I like when characters in A story can be reasonable and work out their problems without all the drama. Ana and Rachel are those characters. There's A few witty moments in this book that made me smile and laugh out loud A few times throughout this story. The supporting characters were written well and helped to make this an even better reading experience. I will definitely be on the lookout for more books by this author.

So good
Format: Paperback
When your one-night stand turns out to be the surgeon that you subpoenaed for a malpractice lawsuit.
Ana, an unappreciated lawyer, has been passed up for promotion to her male colleagues yet again. A malpractice lawsuit win could be what she needs to finally get the promotion she’s worked so hard for. Rachel, a cardiac surgeon who goes above and beyond for her patients, is subpoenaed to testify in a malpractice lawsuit. Arriving at the law firm for her deposition, Rachel discovers that the lawyer for the family who filed the lawsuit is Ana Mendez. As in Ana, her one-night stand.
I was excited to get my hands on this one! I loved that Ana and Rachel were so different from each other in personalities, looks, backgrounds, and religions. The differences made them unique and interesting to me. The banter was well-written, and I loved how feisty they were towards each other in the beginning. Was the dirty talk unexpected? Very much so. I was not prepared for that or for how hot things had gotten. And while I did enjoy the spice, I would’ve liked for there to have been more communication about the conflict too. The references to The Golden Girls and The Sims? Oh, I totally geeked out over that! Overall, it was a good sapphic romance that I’m sure others will enjoy.
I’d like to thank NetGalley and Bold Strokes Books for the arc. This is my voluntary review.
