MAXIM INTEGRATED PRODUCTS MAX1472AKA+T RF TRANSMITTER, 300-450MHZ, SOT-23-8The MAX1472AKA+T is a 300MHz to 450MHz, low power, crystal based ASK transmitter in 8 pin SOT 23 package. This highly integrated crystal referenced phase locked loop (PLL) VHF UHF transmitter designed to transmit OOK ASK data in 300MHz to 450MHz frequency range. The MAX1472 supports data rates up to 100Kbps and adjustable output power to more than +10dBm in to 50 ohm load. The crystal based architecture of MAX1472 eliminates many of the common
The MAX1472AKA+T is a 300MHz to 450MHz, low power, crystal based ASK transmitter in 8 pin SOT-23 package. This highly integrated crystal referenced phase locked loop (PLL) VHF/UHF transmitter designed to transmit OOK/ASK data in 300MHz to 450MHz frequency range. The MAX1472 supports data rates up to 100Kbps and adjustable output power to more than +10dBm in to 50 ohm load. The crystal based architecture of MAX1472 eliminates many of the common problems with SAW transmitters by providing greater modulation depth, faster frequency settling, higher tolerance of transmit frequency and reduced temperature dependence. These improvements enable better overall receiver performance when using a superheterodyne receiver such as MAX1470 or MAX1473. The MAX1472 is used in remote keyless entry, RF remote controls, tire pressure monitoring and radio controlled toys.

Lovely!
I have been using this Kojic Acid and Papaya body lotion, and it is just a lovely lotion with a great scent. That papaya gives it such a sweet, tropical aroma that makes me feel like I’m on a bit of a vacation every time I put it on after my morning shower.
It’s been very hydrating for my skin, and I’ve noticed it has a nice exfoliating quality that helps smooth out those rough patches, especially on my elbows and knees. It’s a real comfort to know that it’s vegan and paraben-free, so I don't have to worry about any harsh chemicals while I’m trying to take care of sun-damaged areas. The 8.45-ounce bottle is a perfect size for the vanity, and the lotion itself sinks right in without leaving me feeling greasy, which is a real plus when I’m trying to get dressed in a hurry.

Pros and cons at once
It smooths and brightens my skin, but it’s not very moisturizing, so I have to reapply it frequently. Expensive too
