illustrate

The LMV225/LMV226/LMV228 are detectors with 30 dB RF power for CDMA and WCDMA applications. The device has an RF frequency range from 450 MHz to 2 GHz. It provides an accurate linear relationship between temperature and power supply compensation for output voltage in dBm of RF input power. The circuit operates from a single 2.7V to 5.5V supply. The LMV225/LMV226/LMV228 have a low ripple CDMA signal with an average power of 30 dB dynamic range detection integrated filter. Other filtration can be applied using an external capacitor.

The LMV225 has an RF power sensing range from -30 dBm to 0 dBm and is ideal for direct use in a combination of resistor taps. The LMV226/LMV228 have a detection range from -15 dBm to 15 dBm and are meant to use directional couplers in combination. The LMV226 is equipped with a buffered output, which makes it suitable for GSM, EDGE, GPRS and TDMA applications.

The device is active enabled = hello, otherwise it is in a low-power shutdown mode. When shutting down, the output will be low. The output voltage ranges from 0.2V to 2V and can be scaled down to meet the input range requirements of the ADC.

The LMV225/LMV226/LMV228 power detectors are available in thin 1.0 mm × 1.0 mm × 0.6 mm micro SMD packages and ultra-thin 1.0 mm × 1.0 mm × 0.35 mm micro SMD packages. The LMV225 and LMV228 are also available in 2.2mm x 2.5mm x 0.8mm LLP packages.
