RFSA2113
Wide Bandwidth Voltage Controlled Attenuator
®
Product Description
The RFSA2113 is a fully monolithic analog voltage
controlled attenuator (VCA) featuring exceptional linearity
over a typical temperature compensated 30 dB gain control
range. The RFSA2113 features a wide bandwidth up to
18 GHz. This VCA 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.

The RFSA2113 attenuation level is set by a single positive
control voltage with on chip DC conditioning circuitry. The
slope polarity of the control voltage versus gain is
selectable. The RFSA2113 draws a very low 2 mA current.
This attenuator is matched to 50 Ω over its rated control
range and frequency with no external matching
components required.

Applications
 Point to Point Radio
Functional Block Diagram
 Test Instrumentation
Typical VCA’s in this performance range are based on
compound semiconductor GaAs FET MMICs that require 1
to 2 negative voltages for control. This game changing
product incorporates the complete solution in a small
3.2 mm x 3.2 mm multi-chip laminate module that reduces
the footprint in area and simplifies the control aspects over
conventional
compound
semiconductor
attenuator
approaches.
