BLA0912-250
Avionics LDMOS transistor
Rev. 02 — 22 July 2004
Product data sheet
1. Product profile
1.1 General description
Silicon N-channel enhancement mode lateral D-MOS transistor encapsulated in a 2-lead
SOT502A flange package with a ceramic cap. The common source is connected to the
mounting flange.
1.2 Features
s High power gain
s Easy power control
s Excellent ruggedness
s Source on mounting base eliminates DC isolators, reducing common mode
inductance.
1.3 Applications
s Avionics transmitter applications in the 960 MHz to 1215 MHz frequency range such
as Mode-S, TCAS and JTIDS, DME or TACAN.
1.4 Quick reference data
Table 1: Quick reference data
Typical RF performance measured in common source class-AB circuit at PL = 250 W and 960 MHz to 1215 MHz frequency
band. Th = 25 °C; Zth = 0.15 K/W; unless specified otherwise.

11. Definitions
12. Disclaimers
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
