Part Number Package Remark SE2527L 16 Pin QFN Samples SE2527L-R 16 Pin QFN Tape and Reel Product Description The SE2527L 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 SE2527L also offers a high power mode by operating at 5 V. This pr ovides an extra 2 dB of improved EVM performance. The SE2527L includes a digital enable control for device on/off control. The device is pin for pin compatible to SiGe’s SE2524L, allowing both devices to share the same application board with only a few component changes required. This provides users with both a high and low power solution without changing the layout. The SE2527L 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.
