Variable Analogue
Phase Shifter
17-21 GHz

Product Datasheet

K-PS-1721

A MMIC analogue phase-shifter enabling morethan 350ᵒ phase variation across the 17–21 GHz
frequency band.

Overview

With excellent matching and very low insertion
loss variation over all phases and frequencies(±1.9 dB), and excellent phase tracking overthe complete frequency range (less than ±15ᵒ),this MMIC offers an alternative to digital phaseshifters where any required phase delay isachievable with the phase set by varying thecontrol voltage (VD) in the range of -0.5 to 0.7 V.

•••••

As the underside of the die is gold plated, thisMMIC is compatible with precision die attach
methods, as well as thermo-compression andthermosonic wire bonding, making it ideal for
MCM and hybrid microcircuit applications.

Connection Configurations

General Notes On Assembly

Die should be mounted on conductive material such as gold-plated metal toprovide a good ground and suitable heat sink, if necessary.
1. Attaching the die using Au/Sn preforms is preferable. The Eutectic
melt for Au/Sn occurs at approximately 280 oC so the die (plus mountand preform) is initially heated up to 180 oC and then it is heated forapproximately 10 seconds to 280 oC using a nitrogen heat gun. The
device will survive 10 seconds at this temperature. The static breakdownfor GaAs devices is approximately 330oC.
2. Pure, dry nitrogen should be used as the heat source.
3. If the device cannot be lifted/ placed by a vacuum device, then ESD dielifting tweezers are preferable.
4. Aluminium wire must not be used.
