2.45 GHz low voltage RF transceiver

DESCRIPTION
The SA2421 transceiver is a combined low–noise amplifier, receive
mixer, transmit mixer and LO buffer IC designed using a 20 GHz f
T
BiCMOS process, QUBiC2, for high–performance low–power
communication systems for 2.4–2.5 GHz applications. The LNA has
a 3.2 dB noise figure at 2.45 GHz with 14.3 dB gain and an IP3
intercept of –3 dBm at the input. The wide–dynamic–range receive
mixer has a 11.2 dB noise figure and an input IP3 of +2.5 dBm at
2.45 GHz. The nominal current drawn from a single 3 V supply is
34 mA in transmit mode and 20 mA in receive mode. The SA2421
differs from the SA2420 by removal of the LO doubler and LO
switch. The LNA reverse isolation is improved, and a separate pin is
allocated for the transmit output.
FEATURES
Low current consumption: 34 mA nominal transmit mode and
20 mA nominal receive mode
High system power gain: 24 dB (LNA + Mixer) at 2.45 GHz
Excellent gain stability versus temperature and supply voltage
Separate Rx IN and Tx OUT pins
Wide IF range: 50–500 MHz
–10dBm typical LO input power
Improved LNA reverse isolation S12
