Functional Diagram
in
ar
The
HMC346ALP3
&
HMC346ALP3E
are
pabsorptive Voltage Variable Attenuators (VVA) in
low cost leadless surface mount plastic packages
operating f r o m D C - 1 4 G H z . I t f e a t u r e s a n
o n - c h i p r e f e r e n c e attenuator for use with an
external op-amp to provide simple single voltage
attenuation control, 0 to -3V. The device is ideal
in designs where an analog DC control signal must
control RF signal levels over a 30 dB amplitude
range. This VVA is an excellent alternative to the
HMC121C8.
