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.

This stuff is really great!
Love this body lotion! Fell in love with it during our stay at the Hale Koa in hawaii. Perfect ! Also thrilled I can buy in bulk! Scent is very light and just what I like. Super moisturizing, without being heavy, sticky, or greasy. We packaged and arrived quickly. Will buy again. Thank you!
