MICRF620

434MHz ISM Band Transceiver Module

General Description

The MICRF620 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 European Telecommunication

Standard Institute (ETSI) specification, EN300 220.

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 filters. The receiver consists of a low noise

amplifier (LNA) that drives a quadrature mix pair. The

mixer outputs feed two identical 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
