2.4 GHz Power Amplifier with Power Detector

Please note: SE2598L-R is being discontinued and is not recommended for new designs. The suggested replacement are SE2622L-R, SKY55200-18, SKY55200-18A

The SE2598L is a 2.4 GHz power amplifier designed for use in the 2.4 GHz ISM band for wireless LAN applications. The device incorporates a power detector for closed loop monitoring of the output power.

The SE2598L includes a digital enable control for device on/off control.

The SE2598L temperature compensated power detector is highly immune to mismatch at its output with less than 1.5 dB of variation with a 2:1 mismatch.
