MICRF600
902-928MHz ISM Band Transceiver
Module
General Description
The MICRF600 is a self-contained frequency shift keying (FSK)
transceiver module, intended for use in half-duplex, bidirectional
RF links. The multi-channeled FSK transceiver module is intended
for UHF radio equipment in compliance with the North American
Federal Communications Commission (FCC) part 15.247 and
249.
The transmitter consists of a fully programmable PLL frequency
synthesizer and power amplifier. The frequency synthesizer

consists of a voltage-controlled oscillator (VCO), a crystal
oscillator, dual modulus prescaler, programmable frequency
dividers, and a phase-detector. The output power of the power
amplifier can be programmed to seven levels. A lock-detect circuit
detects when the PLL is in lock.
In receive mode, the PLL synthesizer generates the local oscillator
(LO) signal. The N, M, and A values that give the LO frequency
are stored in the N0, M0, and A0 registers.
The receiver is a zero intermediate frequency (IF) type that makes
channel filtering possible with low-power, integrated low-pass

signal channels in phase quadrature. Each channel includes a
pre-amplifier, a third order Sallen-Key RC low-pass filter that
protects the following switched-capacitor filter from strong adjacent
channel signals, and a limiter. The main channel filter is a
switched-capacitor implementation of a six-pole elliptic low pass
filter. The cut-off frequency of the Sallen-Key RC filter can be
programmed to four different frequencies: 100kHz, 150kHz,
230kHz, and 350kHz. The I and Q channel outputs are
demodulated and produce a digital data output. The demodulator

detects the relative phase of the I and the Q channel signal. If the I
channel signal lags behind the Q channel, the FSK tone
frequency is above the LO frequency (data “1”). If the I channel
leads the Q channel, then the FSK tone is below the LO
frequency (data “0”). The output of the receiver is available on the
DataIXO pin. A receive signal strength indicator (RSSI) circuit
indicates the received signal level. All support documentation can
