Integra Technologies introduces the IGN1214L500B long-pulse transistor with GaN on SiC HEMT technology, operating at 380 W for applications from 1.2 – 1.4 GHz. The transistor exhibits 15.5 dB typical gain, and 65% efficiency, at 2 milliseconds and 20% pulse conditions. It is specified for use under Class AB operation.

The new VRF152 from Microsemi is a gold-metalized silicon n-channel RF power transistor designed for broadband commercial and hi-rel applications requiring high power and gain without compromising reliability, ruggedness, or inter-modulations distortion. It can operate up to 175MHz at 150W with a typical gain of 13dB at very high efficiency on a 50V DC supply.

The HF50-250 is a 50V epitaxial silicon NPN planar transistor designed primarily for SSB communications. This device utilizes emitter ballasting to achieve extreme ruggedness and reliability.

Microsemi’s new S-Band power modules provide a complete design solution, combining two Microsemi transistors in hermetically sealed packages, with input/output circuitry matched to 50 ohm. Their high performance specifications feature excellent rated power with greater than 40% collector efficiency and superior power flatness of less than 0.5 dB. The transistors utilize advanced Microsemi chip design and processing enhancements for high power and high gain with a 100us pulse width and 10% duty cycle over the S-Band frequency range.

Integra Technologies introduces the IGN1214M380C GaN/SiC transistor, exhibiting 20 dB gain, 54% efficiency at 150 us-10% pulse conditions, and operation in the 1210-1400 MHz frequency range. These devices are 100% tested for large signal parameters.

The QPD1009 and QPD1010 are discrete GaN on SiC HEMTs operating from the DC to 4 GHz frequency range. The QPD1009 is a 15W, 50V device with an output power level of 17W at 2 GHz, and a linear gain of 24 dB at 2 GHz. The 10W, 50V QPD1010 features an output power of 11W at 2 GHz and a linear gain of 24.7 dB at 2 GHz. These two devices are housed in low thermal resistance 3 x 3 mm packages, and are ideal for wideband or narrowband amplifiers, jammers, and for military radar, civilian radar, land mobile, military radio, and test instrumentation applications.
