Product Description

RFMD’s RFSA2033 is a fully monolithic analog voltage controlled attenuator (VCA)

featuring exceptional linearity over a typical temperature-compensated 25dB gain

control range and low insertion loss of 1.0dB typical. It incorporates a

revolutionary new circuit architecture to solve a long standing industry problem:

high IP3, high attenuation range, low DC current, broad bandwidth, and

temperature-compensated linear in dB control voltage characteristic. This voltage

controlled attenuator is controlled by a single positive control voltage with on chip

DC conditioning circuitry. The slope polarity of the control voltage versus gain is

selectable. The RFSA2033 draws a very low 2.5mA current. This attenuator is

matched to 50Ω over its rated control range and frequency with no external

matching components require. Typical VCA’s in this performance category have

poor inherent attenuation versus temperature and poor nonlinear attenuation

versus control voltage characteristics. To correct these shortcomings, other VCA’s

require extensive off chip analog support circuitry that consume valuable PCB

area and additional DC power. This game changing product incorporates the

complete solution in a small 3mm x 3mm QFN package that reduces the footprint

in area and reduces the DC power over conventional PIN diode approaches.
