Millimeter Wave Components
Ka-band P-I-N Diode Switch
P-i-n diode switches are used for control of power in millimeter (mm) wave circuits and are widely used in EW and radar systems. They are primarily used to route signals between ports. Switches using p-i-n diodes as the control device are most common because of fast switching, low insertion loss and high isolation. In addition, the solid-state switches offer high reliability and low drive requirement. P-i-n diode switches can also be used as pulse modulators. The switches are manufactured by M/s CEL, Sahibabad.
Ka-band Balanced Mixer
Mixers are frequency conversion components used for converting high frequencies into a convenient intermeDIATe frequency range. The mixer consists of matching circuits for RF and LO ports, Schottky diodes as mixing elements, and matching/filter circuit for IF port. Balanced mixer has been constructed using standard hybrid MIC techniques. This mixer is manufactured by M/s CEL, Sahibabad.
Ka-band Dielectric Resonator Oscillator
It is a fixed frequency, highly stable oscillator with low phase noise. The oscillator uses a Gunn diode, appropriate matching circuit, and a high Q dielectric resonator as a frequency-stabilising element. Highly stable and low phase noise single frequency dielectric resonator oscillator finds application as local oscillators in radar, communication, and EW systems. This item is being manufactured by M/s CEL, Sahibabad.
