GaAs MMIC for
2.4GHz Wireless
Lan Applications
The P35-4710-1 is a high performance Gallium Arsenide
Monolithic Microwave Integrated Circuit (GaAs MMIC)
transceiver for wireless LAN applications in the 2.4GHz ISM
band. Low receive current requirements make it particularly
useful for battery powered operation.
Features
Extremely low standby current
for whole chip (<0.5mA)
On chip VCO
Balanced IF input/output
Differential LO is provided for
PLL drive
Low LO leakage
No external biasing, or
matching components required
