Wolfspeed extends GaN HEMT family for UHF radar market

Wolfspeed, a Cree Company, has extended its family of 50 V transistors and introduced a gallium nitride (GaN) high electron mobility transistor (HEMT).

The device was created for the growing ultra-high frequency (UHF) radar market, in which defense, public safety and land mobile radio applications seek to upgrade performance and component lifecycle availability by implementing GaN RF power devices. The new UHF GaN RF device delivers greater power density and output power than competing Si LDMOS devices, enabling radar applications to benefit from greater range within the same design footprint.

The new device, CGHV40180, is available in flange and pill package styles and designed to optimize performance for radar power amplifiers, as well as military communications applications from 20 – 1000 MHz. These additional applications include very-high frequency (VHF) and UHF public safety radios and UHF tactical radios. At 250W typical output power, the new device delivers up to 67% more continuous wave (CW) power than traditional Si devices in the same size package, providing significantly more signal range for greater detection and discrimination capabilities that are critical to defense and public safety.

The CGHV40180 features the highest output power in its class with 270W CW typical output power from 800 – 1,000 MHz. Additionally, the device offers low power consumption with 75 percent drain efficiency. GaN HEMTs offer high efficiency, high gain and wide bandwidth capabilities, making the CGHV40180 ideal for linear and compressed amplifier circuits.

A medal for mobile medicine?
Medical services the world over are coming under great pressure to deliver high-quality healthcare and, at the same time control costs. Alongside this, patients are becoming far more involved in their wellbeing as well as wanting a high standard of healthcare with even greater convenience than before. As people are more mobile these days, mobile healthcare (mHealth) avoids the need to visit the doctor’s office and allows patients to provide health data to providers, as well as receive care, anywhere on the planet.
