TH7120
300 to 930MHz
FSK/FM/ASK Transceiver
Features
! Single chip solution with only a few external components
! Stand-alone fixed-frequency transceiver operation modes
! Programmable multi-channel transceiver operation modes
! Low current consumption in active mode and very low standby current
! PLL-stabilized RF VCO (LO) with internal varactor diode
! Lock detection in programmable channel applications
! 3wire bus serial control interface
! FSK/ASK modulation selection
! FSK for digital data and FM for analog signal reception
! RSSI allows signal strength indication and ASK detection
! Switchable LNA gain for improved dynamic range
! Automatic PA turn-on after PLL lock
! FM possible with external varactor
! ASK modulation achieved by on/off keying
! AFC option for extended input frequency acceptance range
! Surface mount package LQFP32
