TH71102
315/433MHz
FSK/FM/ASK Receiver
Features
! Double superhet architecture for high degree of image rejection
! FSK for digital data and FM reception for analog signal transmission
! FM/FSK demodulation with phase-coincidence demodulator
! Low current consumption in active mode and very low standby current
! Switchable LNA gain for improved dynamic range
! RSSI allows signal strength indication and ASK detection
! Surface mount package LQFP32

! Pagers
Technical Data Overview
! Input frequency range: 300 MHz to 450 MHz
! Power supply range: 2.5 V to 5.5 V
! Temperature range: -40 °C to +85 °C
! Operating current: 6.5 mA at low gain and 8.2 mA at high gain mode
! Standby current: < 100 nA
! Sensitivity: -111 dBm 1) with 40 kHz second IF filter BW (incl. SAW front-end filter loss)
! Sensitivity: -104 dBm 2) with 150 kHz second IF filter BW (incl. SAW front-end filter loss)
! Range of first IF: 10 MHz to 80 MHz
! Range of second IF: 455 kHz to 21.4 MHz
! Maximum input level: –10 dBm at ASK and 0 dBm at FSK
! Image rejection: > 65 dB (e.g. with SAW front-end filter and at 10.7 MHz 2nd IF)
! Spurious emission: < -70 dBm
! Input frequency acceptance: ±50 kHz (with AFC option)
! RSSI range: 70 dB
! Frequency deviation range: ±5 kHz to ±120 kHz
! Maximum data rate: 80 kbit/s NRZ
! Maximum analog modulation frequency: 15 kHz
1) at ± 8 kHz FSK deviation, BER = 3⋅10-3 and phase-coincidence demodulation
2) at ± 50 kHz FSK deviation, BER = 3⋅10-3 and phase-coincidence demodulation
