LMV225/LMV226/LMV228 RF power detectors for CDMA and WCDMA provide 30 dB linear in dB power output voltage.
The LMV225, LMV226, and LMV228 are 30 dB RF power detectors designed for CDMA, WCDMA, GSM, EDGE, GPRS and TDMA applications. They operate from 450 MHz to 2 GHz and provide a temperature‑compensated output voltage that is linear to the RF input power in dBm.
These devices are offered in a 1.0 mm × 1.0 mm × 0.6 mm micro‑SMD package and, for LMV225 and LMV228, also in a 2.2 mm × 2.5 mm × 0.8 mm LLP package. They feature a logic‑low shutdown mode, a supply range of 2.7 V‑5.5 V, and an output voltage range of 0.2 V‑2 V.

They operate from 2.7 V up to 5.5 V.
The output voltage varies between 0.2 V and 2 V.
Both the micro‑SMD (1.0 mm × 1.0 mm × 0.6 mm) and the LLP (2.2 mm × 2.5 mm × 0.8 mm) packages are offered.
It detects RF power from –15 dBm to +15 dBm.
