The X-MWsystem from X-Microwave is a complete modular building block eco-system including a broad offering of RF and microwave components, an innovative Prototype Station and a FREE online System Simulator.  The X-MWsystem can be used to seamlessly navigate thru the product development process from simulation to prototype to production hardware.

Marki Microwave has a variety of circuit lines of Broadband RF, Microwave, and Millimeter Wave Mixers.
The HBM series broadband balanced mixers cover the waveguide bands from 18–110 GHz. They utilize a low loss structure mated to a matched pair of GaAs Schottky beam lead diodes for minimum conversion loss and maximum bandwidth. Superior LO noise suppression and LO-RF isolation values are inherent design features

This direct IQ demodulator down-converts RF signals to analog In-phase and Quadrature IF or IQ baseband components. It’s ideal for RF instrumentation, wireless communications, broadcast monitoring, spectral analysis, and software-defined radio applications.

The ML12002 is a double balanced analog mixer, including an input amplifier feeding the mixer carrier port and a temperature compensated bias regulator. The input circuits for both the amplifier and mixer are differential amplifier circuits. The on-chip regulator provides all of the required biasing.
The HHM series broadband harmonic mixers cover full waveguide bands from 18 – 110 GHz. They utilize a low loss finline structure mated to a GaAs Schottky beam lead diode for minimum conversion loss and maximum bandwidth

These Ka band I/Q mixers are ideal for Radar Receiver applications and Single-Sideband Mixers. The LO port is spilt by a 90-degree hybrid to the two mixers. The LO input is buffered so that only 0 dBm of LO power is required for the mixer to operate. These mixers may also be ordered without the integrated LO amplifier.

This W-Band quadrature (I/Q) mixer is ideal for applications involving ranging radar systems, phase detectors, communication systems, and test instrumentation.
