Description

The SA2420 transceiver 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°C 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.

Features

• Low current consumption: 37mA nominal transmit mode and 22mA nominal receive mode
• Fabricated on a high Volume, rugged BiCMOS technology
• High system power gain: 22.5dB (LNA + Mixer) at 2.45GHz
• TSSOP24 package
• Excellent gain stability versus temperature and supply Voltage
• -10dBm LO input power can be used to drive the mixer
• Operates with either full or half frequency LO
• Wide IF range: 50-500MHz

Applications

• 2.45GHz WLAN front-end (802.11, ISM)
