S-BAND / UHF TRANSCEIVER – USER MANUAL SYSTEM DESCRIPTION The S-band transceiver works in the frequency range 2400 – 2480 MHz with GFSK modulation. In the core of this S-band transceiver there is a high performance IC which is a zero-IF transceiver. It is responsible for the output signal forming and also down converting and demodulating of the input signal. - Page 8 S-BAND / UHF TRANSCEIVER – USER MANUAL The UHF transceiver works in the frequency range 430 – 440 MHz with GFSK modulation. In the core of this UHF transceiver there is a high performance IC which is a zero-IF transceiver.
