ADVANCED Power Technology RF's Military & Aerospace Division (APT-RF) has launched a new product family of high power transistors targeting the High L-Band (1480MHz to 1650MHz) Pulsed Radar Applications.
These new products use newer chip designs and processing enhancements to offer state-of-the art performance, notably in high power and high gain over the specified frequency range with 200us pulse width and 10% duty cycle.
The High L-Band series transistors consist of three model types: 1517-20M, 1517-110M and 1517-250M which cover the frequency for High L-Band Radar Applications from 1480MHz to 1650MHz with a pulsed output power of 20W, 110W and 250W respectively.
These transistors are designed to handle medium pulse widths of 200us with a duty cycle of 10%.
The high performance, common base, class C, output stage, for example, offers unparalleled performance of 250W of peak power, 40% collector efficiency and extremely low droop, 0.5dB or less, across the 200us pulse width.
This performance is achieved with the latest APT- RF Si bipolar junction transistor high power technology.
