General Description

A 500 W LDMOS RF Power transistor for broadcast transmitter applications and industrial applications in the HF/VHF band.

Table 1: Typical performance Typical RF performance at VDS = 32 V and Th = 25 °C in a common-source 225 MHz test circuit.[1] Mode of operation CW, class AB 2-tone, class AB [1] f (MHz) 225 f1 = 225;

f2 = 225.1 PL (W) 500 - PL(PEP) (W) 500 Gp (dB) 18 19 ηD (%) 60 47 IMD3 (dBc) −28 Th is the heatsink temperature.

Key Features

  • I Typical CW performance at 225 MHz, a drain-source voltage VDS of 32 V and a quiescent drain current IDq = 2 × 1.0 A: N Load power PL = 500 W N Gain Gp ≥ 18 dB N Drain efficiency ηD = 60 % I Advanced flange material for optimum thermal behavior and reliability I Excellent ruggedness I High power gain I Designed for broadband operation (HF/VHF band) I Source on underside eliminates DC isolators, reducing common-mode inductance I Easy power control 1.3.
