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

The SE2525L‘s bias architecture provides for lower

current consumption at lower output power levels.

Selectable integrated external or internal coupled

temperature compensated power detector

Also, the devices bias (V ) control allows for further

minor customization of the bias current for power

saving at lower output powers.

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

)

The SE2525L includes a digital enable control for

device on/off control.

Small plastic package, 16 pin 4 mm x 4 mm QFN

The SE2525L has two selectable power detectors.

The internally coupled signal is selected by grounding

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.
