SA2420 Description
The SA2420 transceiver is a bined low-noise amplifier, receive mixer, transmit mixer and LO buffer IC designed for high-performance low-power munication 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 pensation to vary less than ±0.2dB over the -40 to +85°C temperature range.
SA2420 Key Features
- Low current consumption: 37mA nominal transmit mode and
- 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
