CAE - Electrical Controlled Attenuators

CAE series are discrete or MMIC PIN diode or HEMT devices based current or voltage controlled electrical attenuators that operate at the frequency range from DC to 110 GHz. These attenuators are especially designed for low insertion loss and high attenuation applications. While PIN diode based attenuators are designed for waveguide bandwidth operation from 18 to 110 GHz, the MMIC based attenuators are designed for broadband operation from DC up to 50 GHz. The maximum attenuation value up to 100 dB is available.

Model CP4T-77303030-D2 and CP10T-77308030-D2 are PIN diode based SP10T and SP4T switches that operate at the RF frequency range from 75 to 78 GHz. These switches are offered with a built-in TTL driver to simplify the channel switching and to reduce the switching time. The DC and logic control ports are accessed via a single Molex miniature connector. The RF interface of the switches WR-10 waveguide with standard UG387/U-M flange on the input and a miniature flange at the outputs. Operational frequency ranges other than 75 to 78 GHz or number of switching channels other than 4 or 10 are available on request.

CAF - Fixed Attenuators

CAF series fixed attenuators are offered for the frequency range of 18 to 110 GHz in seven waveguide bands. The standard attenuation level for fixed attenuators are 3, 6, 10, 20 and 30 dB with full waveguide operational bandwidth. Different attenuation values are available per request. The fixed typically used in the integrated assemblies or bench top test set where certain attenuation is required.

CAL - Level Setting Attenuators

CAL series level setting attenuators are offered for the frequency range of 18 to 110 GHz in seven waveguide bands. The minimum attenuation range for level setting attenuators are from 0 to 30 dB with full waveguide operational bandwidth. The higher attenuation range is available per request. These level setting attenuators are equipped with a micrometer, which enables rapid re-setting. With calibrated charts, the level setting attenuators can be used as direct reading attenuator for bench top test set.

CAR - Direct Reading Attenuators

CAR series direct attenuators are offered for the frequency range of 18 to 110 GHz in seven waveguide bands. The attenuators are constructed with a precision rotary resistive vane in a circular waveguide. Therefore, they are frequency independent.

CPD - SPDT Pin Diode Switches

CPD series are discrete or MMIC based PIN diode Single Pole Double Throw (SPDT) switches that operate at the frequency range from 18 to 110 GHz. These switches are especially designed for low insertion loss and high isolation applications. While these switched are designed for broadband operation, lower insertion loss and higher isolation can be achieved by optimizing design for specific narrower frequency range.
These PIN diode switches are reflective type and can be tailored to absorptive type by integrating input and output isolators. Furthermore, the internal TTL driver is offered as an option for ease TTL control.loss. The standard phase shifters are equipped with micrometer, which allows fine accurate and repeatable phase settings. The variable phase shifters are typically used in the test setups and prototype assemblies where certain phase shifting is required.

CPL - Variable Phase Shifters

CPL series variable phase shifters are offered for the frequency range of 18 to 110 GHz in seven waveguide bands. The phase shifters utilize low loss dielectric material, which offers minimum insertion loss. The standard phase shifters are equipped with micrometer, which allows fine accurate and repeatable phase settings. The variable phase shifters are typically used in the test setups and prototype assemblies where certain phase shifting is required.

CPM - SPMT Pin Diode Switches

CPM series are discrete or MMIC based PIN diode single pole multi-throw (SPMT) switches that operate at the frequency range from 18 to 110 GHz. These switches are especially designed for low insertion loss and high isolation applications. While these switched are designed for broadband operation, lower insertion loss and higher isolation can be achieved by optimizing design for specific narrower frequency range.
