A 20 to 2500 MHz, 20 W Solid-state Amplifier

Aethercomm Inc., San Marcos, CA

Introduction to a 20 to 2500 MHz solid-state power amplifier capable of 10 to 20 W P1dB across the full band

M/A-COM announces a new family of high power broadband amplifiers. The four new amplifiers, MAAPGM0074-DIE, MAAPGM0076-DIE, MAAPGM0077-DIE and MAAPGM0078-DIE can be used in various applications including communications and military electronic systems.

There are a number of communications, radar and imaging applications spanning Ka-band through W-band (26 to 110 GHz) that require transmitter output powers in the range of a few watts to a few tens of watts. Vacuum-tube sources and amplifiers have long been available that can produce output power...

Wireless infrastructure designers must often contend with conflicting goals when developing new equipment for the base transceiver station (BTS) market. The components used in today's systems are frequently required to operate over multiple bands and under multiple modulation formats. The quest for higher performance, lower cost, component interchangeability and...

The performance of communication systems, in both space and ground segments, is degraded by the nonlinearity of the power amplifiers that are operated in saturation to obtain higher efficiency. Linearizing is the technique used to improve the performance of communication systems when power amplifiers are operated in saturation. The...

A line of variable gain amplifiers (VGA) has been introduced for use in transmitter and receiver automatic gain control (AGC) circuits, and as variable gain blocks following low noise amplifier stages in high dynamic range receiver front ends. The new amplifiers integrate high performance amplifiers and attenuators within a...

Two broadband satellite networks are in the final stages of development and plan a service launch for North America in early 2004. Systems like these are expected to provide wideband, high speed communications for Internet and multimedia applications across North America and Europe for years to come. High power...

This article continues the trend of previous publications, 1,2 to simplify the prediction of RF performance of systems designed for wireless digital communications. The first shows the correlation between sidelobes and intermodulation (IM) products. Sidelobes are the result of the spectrum re-growth when a digitally modulated signal is applied...
