MAX7044AKA+T

300MHz to 450MHz High-Efficiency,  Crystal-Based +13dBm ASK Transmitter

射频发射器 300MHz To 450MHz ASK FSK Superhtrdyne Rec

General Description

The MAX7044AKA+T MAX7044 crystal-referenced phase-locked-loop (PLL) VHF/UHF transmitter is designed to transmit OOK/ASK data in the 300MHz to 450MHz frequency range. The MAX7044 supports data rates up to 100kbps, and provides output power up to +13dBm into a 50Ω load while only drawing 7.7mA at 2.7V.

The crystal-based architecture of the MAX7044 eliminates  many of the common problems with SAW-based transmitters  by providing greater modulation depth, faster frequency  settling, higher tolerance of the transmit frequency, and  reduced temperature dependence. The MAX7044 also  features a low supply voltage of +2.1V to +3.6V. These  improvements enable better overall receiver performance  when using the MAX7044 together with a superheterodyne  receiver such as the MAX1470 or MAX1473.
