SE2525L RangeCharger™ 2.4GHz Power Amplifier with Power Detector Preliminary Information Applications 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. DSSS 2.4GHz WLAN (IEEE802.11b) OFDM 2.4GHz WLAN (IEEE802.11g) Access Points, PCMCIA, PC cards Features 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. +19 dBm, EVM = 2.7%, 802.11g, OFDM 54 Mbps +23 dBm, ACPR < -32 dBr, 802.11b +25.5 dBm P1dB at 3.3 V Selectable integrated external or internal coupled temperature compensated power detector Selectable Power Detector Slope for use with multiple chipsets (Negative and Positive) Integrated power amplifier enable pin (VEN) Single supply voltage: 2.7 to 3.6 V Lead free and RoHS Compliant Small plastic package, 16 pin 4 mm x 4 mm QFN 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.
