Quad-Phase (QPSK) ModulatorsProduces 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.
