WL600C

WL600C 2.4 - 2.5GHz RF and IF Circuit Preliminary Information DS4581 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 Mitel 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.
