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.
- Operates from single 3.3V or 5.0V supplies
- Operating temperature range from -40°C to 85°C
- Receiver input frequency range from 300MHz to 450MHz
- High dynamic range with on-chip AGC, selectable image rejection centre frequency
- Selectable x64 or x32 fLO/fXTAL ratio
- Low 5.2mA operating supply current
- Low current power down mode for efficient power cycling < 2.5µA
- 250µs start-up time, built-in 50dB RF image rejection
- Receive sensitivity of -114dBm

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters.
That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception.
SPOILER:
The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured.
I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Fantastic writing and non-stop action
Format: Kindle
This is a promising, fantastic beginning to what will be a 4-book series. Some readers may be content to read only the first 2 books, but I think you'll find that the story is so good that you'll want to keep reading books 3 and 4.
Book 1 is about omega Elvana's introduction to the "Starling" brothers and their search for another missing person, Kelly. It's a bit of a rocky start, with deception and betrayal a key element. Hardly an auspicious beginning. Each member has their own path and purpose in the pack. Their interactions and the resulting narrative are so well-written that I found it difficult to put down.
There is a cliffhanger that will have you reaching for book 2 as you finish, so make sure you have it on hand.

Fun read
Format: Kindle
I'm not really into mafia books but I love Roxy Collin's other series so I decided to give it a try. It had the same great romance, spice, swoon-worthy characters and exciting plot that are her signature. Arben was my favorite, although it was a bit sudden how quickly he changed from ignoring her to wanting to be pack. There were almost too many twists/layers of lies to keep track of but I'm looking forward to reading the other books.
The only thing that detracted from the story for me was the need for a bit more proofreading. It was mentioned that Kelly is a female and male at different points, leading me to think she changed her mind at some point about the character's gender but didn't go back and edit it to align in all places. Like another reviewer pointed out, step siblings are different than half siblings. They are incorrectly referred to as step siblings because they (allegedly) share the same biological dad. There are a few other typos as well but those aren't a big deal.

Stepbrothers, Secrets, and Sizzling Heat
Format: Kindle
Twisted Lies by Roxy Collins is a wild ride through family secrets, amnesia, and a steamy stepbrother romance. When Kelly discovers her life is built on lies, she ends up tangled with three alpha stepbrothers and an assassin who once helped her through a heat.
The tension? Off the charts!
The heat is real, and the complications are messy in the best way. Full of twists, secrets, and fated mates? You'll be hooked from page one!
Love omegaverse drama with a dash of taboo? This one's for you!

Good read
Format: Kindle
The book has some good twists and turns, but truthfully I was so confused on some things. It didn't have a good flow for me personally. Not sure if it's due to typos or using him/her wrongly, but I thought Kelly was both a guy and a girl. Actually I still don't know, and it made me incredibly frustrated. It would refer to Kelley as him or he, and then again in another part of the story as her she and sister. On to the next book, I hope there is some clarity and a smoother flow. This is a slow burn, and I just don't know how much I care for the Alphas yet. Idk if I recommend.
