Philips SA2420
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.| Part No. | SA2420 |
