Industry’s first 1kW LDMOS field effect transistor operating at L-band frequency to be featured at IMS 2009 in Boston

AUSTIN, Texas – June 2, 2009 – Freescale Semiconductor has introduced five laterally diffused metal oxide semiconductor (LDMOS) field effect transistors (FETs) for commercial aerospace applications. The expanded RF portfolio includes L-band (965 MHz to 1215 MHz) devices and the first LDMOS FETs for aerospace applications at S-band (3.1 GHz to 3.5 GHz). Freescale will showcase these devices at Booth #2018 at the International Microwave Symposium (IMS 2009) in Boston, June 7-12.

The RF power transistors are designed to deliver the highest RF output power, efficiency and gain in their class. The exceptionally rugged devices are ideal for pulsed-signal applications, such as air traffic control, distance measuring equipment (DME) and weather radar.

Freescale’s expanded RF portfolio for aerospace applications includes:

• MRF6VP121KH/HS – 965 MHz to 1215 MHz, 1kW peak, (100 W average output), 128 µsec pulse width, 10% duty cycle, 50 Vdc, 20 dB gain, 56% efficiency at 1030 MHz.

• MRF6V12500H/HS – 965 MHz to 1215 MHz, 500 W peak, (50 W average output), 128 µsec pulse width, 10% duty cycle, 50 Vdc, 19 dB gain, 60% efficiency at 1030 MHz. Designed to handle full rated peak power into 10:1 VSWR.

• MRF6V12250H/HS – 965 MHz to 1215 MHz, 275 W peak, (27.5 W average output), 128 µsec pulse width, 10% duty cycle, 50 Vdc, 20.3 dB gain, 65.5% efficiency at 1030 MHz. Designed to handle full rated peak power into 10:1 VSWR.

• MRF7S35120HS – 3.1 GHz to 3.5 GHz, 120 W peak, (24 W average output), 100 µsec pulse width, 20% duty cycle, 32 Vdc, 12 dB gain and 40% efficiency at 3.5 GHz. Designed to handle full rated peak power into 10:1 VSWR.

• MRF7S35015H – 3.1 GHz to 3.5 GHz, 15 W peak, (3 W average output), 100 µsec pulse width, 20% duty cycle, 32 Vdc, 16 dB gain and 41% efficiency at 3.5 GHz. Designed to handle full rated peak power into 10:1 VSWR.

Like other Freescale commercial aerospace RF power transistors, the latest devices are RoHS compliant and incorporate electrostatic discharge (ESD) protection. This ESD circuitry enables a broad gate voltage swing of -6 V to +10 V to help improve performance when the devices are operating in higher efficiency modes, such as Class C.

Pricing and availability
The MRF6VP121KH/HS, MRF6V12250H/HS, MRF7S35120HS and the MRF7S35015H devices are in full production. The MRF6V12500H/HS is expected to be in production in September 2009. All devices are sampling, and reference test fixtures are available now. Large-signal models for L-band devices are expected in September 2009. For sampling and pricing information, please contact a Freescale sales representative or an authorized distributor.
