Band 11 Amplifier. This power amplifier is a 483mm
Rand-Mounting design, incorporating three AM14/30.
Amplifiers driven in parallel from a single AM14/29. The
amplifier requires 2W of drive in the range 88-104MHz to
produce 250W output. Power requirements +34V d.c. 18A
maximum. Supersedes AM14/9. Sub-units AM14/29 and
AM14/30. DD 1978. CANCELLED.
Band 11 R.F. Amplifier 25W. Complements the existing
power amplifier modules AM14/29 (45W), AM14/30 (100W), and
is housed in similar metalwork, forming a series of
mechanically
interchangeable
units
with
identical
input/output connections. Power requirements 34W d.c.
