General Description
SA2421 General Description
The SA2421 transceiver is a combined lownoise amplifier, receive mixer, transmit mixer and LO buffer IC designed using a 20 GHz fT BiCMOS process, QUBiC2, for highperformance lowpower communication systems for 2.42.5 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 widedynamicrange 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.

1. Transients exceeding these conditions may damage the product.
2. Maximum dissipation is determined by the operating ambient temperature and the thermal resistance, and absolute maximum ratings may
impact product reliability JA: 24-Pin TSSOP = 117°C/W
3. IC is protected for ESD voltages up to 2000 V, human body model.
