Product Summary

The SA2420DH is a Low voltage RF transceiver. The SA2420DH is a combined low-noise amplifier, receive mixer, transmit mixer and LO buffer IC designed for high-performance low-power communication systems for 2.4-2.5GHz applications. The LNA has a 2.5dB noise figure at 2.45GHz with 14dB gain and an IP3 intercept of -3dBm at the input. The gain is stabilized by on-chip compensation to vary less than ±0.2dB over the -40 to +85℃ temperature range. The wide-dynamic-range receive mixer has a 10.9dB noise figure and an input IP3 of +2.8dBm at 2.45GHz. The nominal current drawn from a single 3V supply is 37mA in transmit mode and 22mA in receive mode. The application of the SA2420DH includes 2.45GHz WLAN front-end (802.11, ISM).

Parametrics

SA2420DH absolute maximum ratings: (1)Supply voltage, VCC: -0.3 to +6 V; (2)Voltage applied to any pin, VIN: -0.3 to (VCC + 0.3) V; (3)Power dissipation, TA = 25℃ (still air) 24-Pin Plastic TSSOP, PD: 555 mW; (4)Maximum operating junction temperature, TJMAX: 150℃; (5)Maximum power (RF/IF/LO pins), PMAX: +20 dBm; (6)Storage temperature range, TSTG: -65 to +150℃.

Features

SA2420DH features: (1)Low current consumption: 37mA nominal transmit mode and 22mA nominal receive mode; (2)Fabricated on a high volume, rugged BiCMOS technology; (3)High system power gain: 22.5dB (LNA + Mixer) at 2.45GHz; (4)TSSOP24 package; (5)Excellent gain stability versus temperature and supply voltage; (6)-10dBm LO input power can be used to drive the mixer; (7)Operates with either full or half frequency LO; (8)Wide IF range: 50-500MHz.
