MAXIM INTEGRATED PRODUCTS MAX7044AKA+T RF TRANSMITTER, 300-450MHZ, SOT-23-8The MAX7044AKA+T is a 300MHz to 450MHz high efficiency, crystal based +13dBm ASK transmitter in 8 pin SOT 23 package. This crystal referenced phase locked loop (PLL) VHF UHF transmitter is designed to transmit OOK ASK data in 300MHz to 450MHz frequency range. It supports data rates up to 100Kbps and provides output power up to +13dBm into a 50 ohm load while only drawing 7. 7mA at 2. 7V. Crystal based architecture of IC eliminates many of common
The MAX7044AKA+T is a 300MHz to 450MHz high efficiency, crystal based +13dBm ASK transmitter in 8 pin SOT-23 package. This crystal-referenced phase-locked-loop (PLL) VHF/UHF transmitter is designed to transmit OOK/ASK data in 300MHz to 450MHz frequency range. It supports data rates up to 100Kbps and provides output power up to +13dBm into a 50 ohm load while only drawing 7.7mA at 2.7V. Crystal based architecture of IC eliminates many of common problems with SAW based transmitter by providing greater modulation depth, faster frequency settling, higher tolerance of transmit frequency and reduced temperature dependence. A simple, single input data interface and a buffered clock-out signal at 1/16th crystal frequency makes MAX7044 compatible with almost any microcontroller or code hopping generator. It is used in remote keyless entry (RKE), tire pressure monitoring (TPM), garage door openers, wireless game consoles, wireless computer peripherals, wireless sensors & RF remote controls.

Great product
Color: Sand Nickel+Brush Holder
Very happy with this purchase. It is relatively compact so it doesn't take a lot of room in my sink, but big enough to hold sponges and wand. It also gives you the option to hang on wall or sink.

So far so good!
Color: Silver+Brush Holder
It’s only been about a week since I applied it, seems sturdy enough, and the adhesive was sticky enough that it seems secure. I use very hot water to wash dishes due to illnesses and it’s held up well to the heat of the kitchen thus far using just adhesive. Good buy!
