RF Power transistors target airborne distance measuring equipment

HVVi Semiconductors, Inc. announced the company's first products for airborne Distance Measuring Equipment (DME) applications operating in the 1025 to 1150 MHz frequency band. Based on the high voltage vertical field effect transistor (HVVFET) architecture, the HVV1012-060, HVV1012-100 and HVV1012-250 RF transistors are optimized for high output power and gain in a small package.

Designed for L-band avionics applications operating between 1025 MHz to 1150 MHz, the HVV1012-060 RF transistor is designed for 48V operation and delivers over 60W of pulsed output power. The new device delivers 23 dB of gain when pulse width = 10 usec and pulse duty cycle = 1% at VDD = 48V and IDQ = 25 mA. To help boost system reliability, the HVV1012-060 is specified to withstand a 20:1 VSWR over all phase angles at the rated output power and operating voltage across the entire frequency band.

The HVV1012-100 RF transistor is also designed for L-band applications in the 1025 to 1150 MHz frequency band. It also operates off a 48V supply voltage and delivers over 100W of pulsed output power. The new transistor offers a power gain of 20.5 dB under a pulse width of 10 usec and a pulse duty cycle of 1% at VDD = 48V and IDQ = 50 mA. Like the HVV1012-060, the new device is specified to withstand a 20:1 VSWR.

The third product in the family, the HVV1012-250 RF transistor, delivers over 250W of pulsed output power. Operating off a 48V supply, the transistor offers a gain of 20 dB with a pulse width = 10 usec and pulse duty cycle = 1% at VDD = 48V and IDQ = 100 mA. Like the other products in the family, this device is specified to withstand a 20:1 VSWR over all phase angles at the rated output power and operating voltage across the entire frequency band.

All three devices are sampling immediately and are housed in a HV400-style, two-lead metal flanged package with liquid crystal polymer lid. The package is MIL-STD-883 qualified. The HVV1012-060 sells for $199.01 in 1-24 unit quantities, the HVV1012-100 costs $226.15 in 1-24 quantities and the HVV1012-250 is available for $398.31 in 1-24 quantities.
