ILD3135EL20 is a high power LDMOS transistor designed for S-band radar applications operating over the 3.1 - 3.5 GHz instantaneous frequency band. Under 16ms / 50% pulsing conditions it supplies a minimum of 20 W (typically 25-30W) of peak output power with 10dB gain typically. Specified operation is with Class AB bias. The device also may be operated with Class A or B bias. When appropriately rated, it is operable under a wide range of pulse widths and duty factors. It operates with spectral purity into all phases of 3:1 output load VSWR. All devices are 100% screened for large signal RF parameters in a fixed tuned broadband matching circuit / test fixture.
