Millimeter-wave Receivers

These custom-designed millimeter-wave receiver modules are designed for radiometer applications. Two downconverter models have been custom-designed to operate at K-band (20 to 40 GHz) and V-band (50 to 75 GHz). Gain calibration is accomplished using an internal K- or V-band noise source, a noise injection coupler and a precision temperature sensor.

Using a +2.0 dBm Ku-band local oscillator (LO) input to each module, both units employ a sub-harmonic mixer topology to down-convert from the millimeter-wave input frequency to an IF output under 1 GHz, providing 30 dB of nominal gain to the input signal. The V-band module utilizes an additional diode-based frequency doubler on the LO input, allowing a common local oscillator to drive both modules. Overall, the receiver noise figure is under 4 dB for the K-band model and under 6 dB for the V-band receiver.

Silicon CMOS Switch Matrix

This 4 x 2 switch matrix combines a digital decoder with the RF switching network and tone/voltage detect designed for European- and Asian-market applications including Direct Broadcast Satellite (DBS) Low Noise Block (LNB) – the SKY13292-365LF. DBS is a service that allows households to receive television programming directly from a satellite transponder. The LNB is located on the satellite dish antenna and amplifies/downconverts to a 0.7 to 2.15 GHz IF. The switch matrix is responsible for connecting four of the satellite signals to two indoor set-top controllers, selectable by the viewer’s channel choice. The switch is packaged in a lead (Pb)-free and RoHS-compliant, QFN 4 x 4 mm plastic package.
