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.
FEATURES
s Part of DE6038 chipset (WL800, WL102)
s High level of integration
s Low noise figure
s Low power consumption
s High data rates with comparator for 2 level FSK
s Minimal external components
s 48 lead LQFP package
