SE2525L RangeCharger™ 2.4GHz Power Amplifier with Power Detector Preliminary Information Applications DSSS 2.4GHz WLAN (IEEE802.11b) OFDM 2.4GHz WLAN (IEEE802.11g) Access Points, PCMCIA, PC cards Product Description The SE2525L is a 2.4GHz power amplifier designed for use in the 2.4GHz ISM band for wireless LAN applications. The device incorporates two selectable power detectors for closed loop monitoring of the output power. For wireless LAN applications, the device meets the requirements of 802.11g and delivers +19 dBm, at an EVM of 2.7% and current of 160 mA @ 3.3 V. The SE2525L‘s bias architecture provides for lower current consumption at lower output power levels. Also, the devices bias (VB) control allows for further minor customization of the bias current for power saving at lower output powers. The SE2525L includes a digital enable control for device on/off control. The SE2525L has two selectable power detectors. The internally coupled signal is selected by grounding the VDETIN/DETSEL pin. This detector detects signal at the second stage improving the accuracy under output mismatch conditions. The second detector uses an external RF input pin which would typically be taken from a directional coupler output. Both detectors are temperature compensated for minimum component count and high accuracy. Each of these power detectors also have selectable positive and negative slopes for ease of use with all chipsets. Please note this device is not recommended for new designs. SiGe’s SE2528L is a pin for pin compatible device and can be used in existing SE2525L application boards with only component value changes. Application notes are available to assist in the change.
