RF Power Detector for CDMA and WCDMA in micro SMD
LMV225/LMV226/LMV228 Power Detector for CDMA and WCDMA
General Description

The LMV225/LMV226/LMV228 are30dB RF power detec-
tors intendedfor usein CDMA and WCDMA applications.
The device hasanRF frequency range from 450 MHzto2
GHz.It providesan accurate temperature and supply com-
pensated output voltage that relates linearlytotheRF input
powerin dBm. The circuit operates witha single supply from
2.7Vto 5.5V. The LMV225/LMV226/LMV228 havean inte-
grated filterfor low-ripple average power detectionof CDMA
signals with30dB dynamic range. Additional filtering canbe
applied usinga single external capacitor.
The LMV225 hasanRF power detection range from –30
dBmto0 dBm andis ideally suitedfor direct usein combi-
nation with resistive taps. The LMV226/LMV228 havea de-
tection range from –15 dBmto15 dBm and are intendedfor
usein combination witha directional coupler. The LMV226is
equipped witha buffered output which makesit suitablefor
GSM, EDGE, GPRS and TDMA applications.
The deviceis activefor Enable=HI, otherwiseitisina low
power consumption shutdown mode. During shutdown the
outputwillbe LOW. The output voltage ranges from 0.2Vto and canbe scaled downto meet ADC input rangere-
quirements.
The LMV225/LMV226/LMV228 power detectors are offered the small1.0 mmx 1.0 mmX0.6 mm micro SMD pack-
age. The LMV225 and the LMV228 are also offeredin the
2.2 mmx 2.5 mmx 0.8 mm LLP package.
