Section A. Introduction
This document is the MARK-IV Broadband Amplifiers User’s Manual, intended for the
Radio Technical Personnel.
The Mark-IV Broadband Amplifiers are highly-linear devices suitable for applications in the
two-way radio and cellular UHF and 800 MHz bands.
They are intended for use in low to mid power amplification and re-amplification systems,
including land-mobile radio and cellular uni- and bi-directional signal booster systems.
These amplifiers utilize linear LDMOS power devices that provide high gain, wide dynamic
range, and excellent group delay and phase linearity.
Exceptional performance, long term reliability, and high efficiency are achieved by
employing advanced matching networks and combining techniques, EMI/RFI filters,
machined housings, and qualified components.
