Integrated Couplers/ Harmonic Mixers
These waveguide bandwidth integrated coupler/mixers are designed to allow phase locking or signal monitoring of compact millimeter wave systems. RF inputs and outputs are on opposite sides of a thin wafer to obtain minimum insertion length. These devices use silicon Schottky barrier beam-lead diodes on a rugged stripline circuit. Nominal coupling value is 10 dB. For coupling values greater than 10 dB, non-directional coupler models are available (consult factory).

60 GHz WR-15 Waveguide Tx Module
PEM010
The PEM010 is a highly integrated millimeter wave transmitter that covers the 60 GHz global unlicensed spectrum allocations packaged in a standard waveguide module. Transmitter architecture is a double conversion, sliding IF with wide bandwidth capability through the up-conversion chain from baseband to carrier. The I/Q interface accepts analog baseband signals which provides for flexibility in design and applications. The baseband input optionally supports FSK/MSK modulation for non-coherent applications. The transmitter incorporates a complete waveguide interface with low-loss transition between the chip and the WR15 waveguide port. The integrated package is small and lightweight, with a simple to use multi-pin ST4 connector for power, reference clock, digital control port and baseband signals. Either of two reference clocks can be used for setting 540 MHz or 500 MHz channel spacing.

Full Band Noise Figure and Gain Test Extenders
STG-06-S1
Full band noise figure and gain test extenders are offered to extend noise and gain measuring capabilities up to higher millimeterwave frequency ranges. These extenders are designed to interface with noise and gain test systems that have an input IF of 10 MHz to 1.6 GHz, such as the industry standard Keysight 8970A/B, N8975A and Maury MT 2075B. The noise figure and gain test extenders include a high-performance, solid-state noise source (STZ series) and a full waveguide down converter (STC series), which consists of a Faraday isolator (STF series), full band mixer (SFB series), frequency multiplier, and IF amplifier. A frequency source with an output signal in the frequency range of 10 to 20 GHz is required as a local oscillator for the down converter. The noise source is automatically powered on and off by the noise figure meter.

Millimeter Wave Continuously Variable Waveguide Attenuators
Our millimeter wave variable waveguide attenuators allow designers and engineers to test their systems at various signal strengths and attenuation values to determine the optimum signal performance of the system. The key feature of these waveguide attenuators is that the attenuation level is adjusted using a built-in micrometer which enables repeatable and rapid re-setting to different attenuation levels without the need for additional external components. Our waveguide attenuators handle varying attenuation levels from 0 to 30 dB over the specified band allowing the designer to tune the attenuation level needed for the application. These continuously variable waveguide attenuators cover a broad frequency range of 33 to 110 GHz in five bands and also display flat performance across a wide band with low insertion loss.
