WL600C

2.4 - 2.5GHz RF and IF Circuit

Preliminary Information

DS4581

ISSUE 2.1

August 1997

The WL600C is a 2.4-2.5GHz RF transmitter and

receiver chip for use in digital radio, and operates from a

supply voltage of 2.7 - 3.6V. It is designed to work with the

Zarlink Semiconductor WL800 frequency synthesiser and

the WL102 WLAN controller chip which together make up

the DE6038 frequency hopping Wireless Local Area

Network (WLAN) transceiver.

The receiver circuit contains a low noise amplifier,

image rejecting mixer, IF limiting strip with RSSI and a

quadrature demodulator. There is also a power amplifier

driver stage and ramp control facility for use in transmit.
