AMMP-6640

DC-40 GHz Variable Attenuator

Data Sheet

Description

The AMMP-6640 MMIC is a monolithic, voltage variable,

GaAs IC attenuator that operates from DC-40 GHz. It is

fabricated using Avago Technologies enhancement mode

MMIC process with backside ground vias, and gate lengths

of approximately 0.25um. The attenuator has a distributed

topology that helps to absorb parasitic eects of its series

and shunt FETs to make it broadband.

Electrical Specications

1. Small/Large -signal data measured in a fully de-embedded test xture form TA = 25°C.

2. Data obtained from on-wafer measurement

3. This nal package part performance is veried by a functional test correlated to actual performance at one or more

frequencies.

4. Specications are derived from measurements in a 50 Ω test environment. Aspects of the amplier performance may

be improved over a more narrow bandwidth by application of additional conjugate, linearity, or low noise (Гopt)

matching.

AMMP-6640 Biasing and Operation

The AMMP-6640 attenuator is driven by voltage ramps

placed on Vseries and Vshunt control pins. Operation in

this mode requires voltages between 0 to 1.5 volts for Vse

and 0 to 1.5 volts for Vsh. The recommended DC control

voltage range is Vse = 0 to 1.2 volts and Vsh = 0 to 1.2

volts. A simplied schematic for the AMMP-6640 is shown

in Figure 17.

In the minimum attenuation state, the series FETs are

fully biased at 1.2 volts and the shunt FETs are in the full

“o” state at 0 volts. Inversely, for a maximum attenuation

state, the series FETs are “o” at 0 volts bias and the shunt

FETs are fully on at 1.2 volts. Achieving attenuation levels

in-between these two states requires voltage levels similar

to those in Table 4. Applying voltage to the shunt FETs sets

the source to drain resistance and establishes the main

attenuation level. The match is optimized by the amount

of bias applied to the series FETs. The match will determine

how at the attenuation level is across a broadband

operational range.
