HVVi Semiconductors Inc. has released the company's first product for radar applications in the UHF band that uses its High Voltage Vertical Field Effect Transistor architecture. Operating across the 420-470MHz band, the HVV0405-175 is a fully qualified 175W RF power transistor optimized for gain and ruggedness.

The company also announced the HVV0912-150, a power transistor for Distance Measuring Equipment (DME) applications. Operating across a 960-1,215MHz band, the HVV0912-150 is designed for ground-based DME systems that require a wider bandwidth than the company's earlier announced parts for airborne DME applications.

The HVV0405-175 operates across the 420-470MHz band and delivers up to 175W of power. The new device supplies up to 25dB of gain when pulse width = 300?s and pulse duty cycle = 10% at VDD = 50V and IDQ = 50mA. This UHF part withstands an output load mismatch corresponding to a 20:1 VSWR across all phase angles at rated output power and operating voltage across the entire frequency band.

For designers of ground-based DME systems, the HVV0912-150 delivers up to 150W of power. Operating off a 50V supply voltage, the new transistor delivers power gain of 20dB under a pulse width of 10?s and a pulse duty cycle of 10 percent. The HVV0912-150 is specified to withstand a VSWR of 20:1 across all phase angles. The two new devices are sampling immediately and come in a HV400-style, two-lead metal flanged package with liquid crystal polymer lid. Both devices are fully qualified. The HVV0405-175 sells for $280.42 in quantities up to 24 pieces. The HVV0912-150 sells for $316.61 in similar quantities. Both transistors are available through Richardson Electronics.
