Quad-Phase (QPSK) Modulators


Produces up to 9:1 bandwidths from 200 MHz to 22 GHz and options that include ultra-broadband, optimized narrowband, and sub-assembly integration.  Unit-to-unit phase and amplitude matching available along with bi-directional variable phase characteristics from one port to another.  Control options including solder pins or a Multi-Pin Connector.  Narrowband models available from 22.0 GHz to 35.0 GHz with 10% bandwidth.

 

Frequency Ranges:  From 200 MHz to 22 GHz, up to 9:1 bandwidths available as well as any optimization.  Narrowband models available from 22.0 GHz to 35.0 GHz with 10% bandwidth.

 

TTL Compatible Logic:  2 BIT binary logic:

 

E1 E2 Output
0 0 0° Ref
1 0 +270°
1 1 +180°
0 1 +90°

 

High Speed Switching:  QPSK Modulators listed are measured from 50% TTL to 10% / 90% RF from any set value to any set value. 

 

DC Power Consumption:  QPSK Modulators require ±5 VDC @ ±100 mA.

 

Operating Temperature Range:  Standard models include temperature compensation in a range from 0° to +50° C.  For more severe environments, please consult the factory.

 

High RF Power Handling:  For power levels greater than listed, please consult the factory.

 

Standard Interfaces:  RF port connectors are ‘SMA’ female per MIL-C-39012.  DC/Logic connections are solder terminals.  Please consult the factory for additional options.

 

Matched Phase & Amplitude:  Models listed can be matched unit-to-unit.  Please consult the factory.
