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.

Rectangular Horn Antennas
-
SAGE Millimeter wave rectangular gain horns, also called pyramidal gain horns, are offered as both standard and custom models with a rectangular waveguide interface. The pyramidal gain horns only support linear polarization. With a calibrated gain chart, these horns can be used to measure the gain of other antennas by comparing the generated signal levels of both. For this reason, these horns are also referred to as standard gain horns. The listed models offer 23 dB nominal gain, 10/11 degrees typical half power beamwidth and 14 dB/30 dB typical side lobe levels at the center frequency of the band. These horns cover full waveguide bandwidths within the frequency range of 8.2 to 170 GHz. In addition to the models listed below, models with 10, 15, 20 and 25 dB gain and other frequency bands are also available.

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).
