20G-PSDD-8
20G phase shifter withintegrated Doubler & Driver

Description
The 20G-PSDD-8 is an analog phase shifter withintegrated frequency doubler and variable gain stage
with output power amplifier in SMD package.
For an input frequency of 10,7GHz the device delivers
an output signal at 21,4 GHz.
The device is capable of up to 600° phase shift at10GHz. The output amplifier is designed to deliver up
to 8Vpp with low distortion (also included output afilter). The variable gain stage has a wide dynamic
range of 20dB.
A power detector, with reference diode, is also
included, giving a direct measurement of the outputpower.

Features16x16 mm² SMD
48 pins w/1mm pitch
50ΩRF Single ended input and output
RF input and output are AC coupledInput frequency band : 9.9 – 11.5 GHzOutput frequency band : 19.8 – 23 GHz
Wide phase shift >360°(up to 600°) at 10GHz

Handling This product is sensitive to electrostatic
discharge and should not be handled except at a static
free workstation. Take precautions to prevent ESD; usewrist straps, grounded work surfaces and recognizedanti-static techniques when handling the20G-PSDD-8 modules.
Care should be taken to avoid supply transient andover voltage. Over voltage above the maximum
specified in absolute maximum rating section may
cause permanent damage to the device.
