Typical Applications
the HMC973LP3e is ideal for:
" Point-to-Point radio
" Cellular/3G & WiMAX/4G Infrastructure
" test Instrumentation
" Microwave sensors
" Military, eCM & radar
the HMC973LP3e is an absorptive Voltage Variable
Attenuator (VVA) which operates from 0.5 to 6 GHz
and is ideal in designs where an analog DC control
signal must be used to control rF signal levels over
a 26 dB amplitude range. It features a shunt-type
attenuator controlled by an analog voltage, Vctrl. un-
like other GaAs Fet based VVAs the HMC973LP3e
exhibits excellent linearity of +35 dBm input IP3,
throughout its control range. the HMC973LP3e
is an unidirectional device with optimum linearity
performance achieved when the rF input signal is
applied to the rFIn package lead. the HMC973LP3e
is housed in a roHs compliant 3x3 mm QFn leadless
package.
