SBE SB2-LA - Introduction and General Information; General Description; Specifications

I INTRODUCTION AND GENERAL INFORMATION
A. GENERAL DESCRIPTION
Sideband Engineers' Model SB2-LA is a linear amplifier designed primarily
for use with the SB-34 single-sideband transceiver and similar equipment.
The unit is self-contained and operates on the authorized amateur frequencies
within the spectrum 3.8 - 21.45 mc/s. The SB2-LA is capable of peak power
inputs up to 1000 watts (750 watts on 15 meters) and will accept any of the
emission types normally employed in this frequency range (SSB, AM, PM,
HM PS Ke ete. )k
The self-contained power supply operates from a nominal 117-volts AC, 50/60
cycle source. Mobile operation is possible through the use of a solid-state
inverter (Sideband Engineers! Model SB3-DCP) which is available as an acces-
sory item. The linear amplifier is designed for operation into a 50-ohm, un-
balanced antenna load with a vswr of 2:1 or less.
The SB2-LA contains a flexible control system which permits operation with
transceivers (or exciters) other than the SB-33. To obtain full power capability
of the amplifier, approximately 65 watts of drive is required. Operation at
reduced output is possible with lower amounts of drive. The amplifier will
provide approximately 10 db power amplification to any input signal up to
maximum rated power.
