CPPD-0.85-2

Overview

The Crystek Corporation CPPD-0.85-2 is a passive frequency doubler module designed for RF applications. It accepts an input frequency range of 0.85 GHz to 2.0 GHz and multiplies the signal by a factor of two, producing output frequencies from 1.7 GHz to 4.0 GHz. The component supports an input drive level between 10 dBm and 20 dBm. It features typical conversion loss of 15 dB and provides 33 dB typical isolation between the fundamental output (Fo) and the fourth harmonic (4Fo). The device utilizes SMA connectors and is housed in a small inline module package.

Feature Summary

• Passive frequency doubling operation with a multiplication factor of two
• SMA connector interface for seamless integration into RF systems
• High isolation between fundamental and higher-order harmonics

Applications

• RF signal generation circuits requiring frequency multiplication
• Microwave communication system local oscillators
• Test and measurement equipment signal sources

Procurement Notes

Verify the specific datasheet version when sourcing this component, as the part status may be listed as obsolete in some distributor catalogs. Confirm that the required input drive level falls within the 10 dBm to 20 dBm range for your application. Ensure compatibility with the SMA connector type and inline module form factor during procurement planning.

Selection Notes

Select this component when a passive solution is needed to double frequencies between 0.85 GHz and 2.0 GHz. Consider the 15 dB typical conversion loss impact on system gain budget. Verify that the input power requirements align with available driver stages. The inline SMA design simplifies PCB layout compared to surface-mount alternatives.

Part Context

This component belongs to the Crystek CPPD line of pocket passive doublers.
