IRVINE, Calif. Pasternack, an Infinite Electronics brand and provider of radio frequency (RF), microwave, and millimeter wave products, has launched a new series of high-power RF and microwave PIN diode coaxial packaged switches that are designed for commercial and military radar, jamming systems, medical imaging, communications, and electronic warfare (EW).

According to the company, Pasternack's new high-power RF and microwave PIN diode switches utilize gallium nitride (GaN) semiconductor technology. GaN and chip & wire technology in the manufacturing process is intended to ensure power performance with a power-to-volume ratio that is ideal for broadband high power applications.

These PIN diode switches are designed to offer thermal properties and a higher breakdown voltage that aims to result in tolerating higher input power levels over broadband and narrowband RF and microwave frequencies. Because these are PIN diode designs, they also offer fast switching speed.

The company also claims that other features include cold switching performance up to 100 watts CW RF input power, broad frequency band coverage ranging from DC to 18 GHz with reflective SPDT and SP4T PIN diode designs, TTL compatible driver circuitry for accurate logic control, and compact coaxial packages.
