Transient Protection of Darlington gain block amplifiers

EBook Description: Monolithic wideband amplifiers are widely used in the RF and microwave systems. Many of these amplifiers use Darlington configuration. Mini-Circuits monolithic amplifiers with model prefix MAR and ERA, for example, use this configuration.

The LZY-1 is a low cost, rugged, versatile, 43 dB Typ. gain, broadband, Class A Linear RF Power Amplifier Module designed to operate linearly over the 20 MHz to 512 MHz frequency
band.

Ultra Linear 32W Amplifiers 500 1000MHz (LZY 2)

The LZY-2+ is a low cost, rugged, versatile, 40dB Gain (minimum), Broadband, Class A Linear RF Power Amplifier designed to operate linearly over the 500MHz to 1000MHz
frequency band. The LZY-2+ features low compression and low harmonic distortion at
20 watts, which make it ideally suited to a wide variety of AM, FM, Pulse and MultiCarrier applications including cellular service in FEEDFORWARD amplifiers as a Pre
Amplifier, Main Amplifier or Error Amplifier.

Uses and Advantages of quot;MERAquot; Dual Matched MMIC Amplifiers

The Mini-Circuits ERA and Gali series of amplifiers are monolithic HBT devices in Darlington configuration. They are wide band 50-ohm amplifiers that are easy to use, as they require very few external components.

Using the Catalog Specifications to Determine MMIC Reliability

Specification pages for MMIC (Microwave Monolithic Integrated Circuit) amplifiers in the Mini-Circuits catalog contain graphs of typical MTTF (Mean-Time-To-Failure) as a function of Junction Temperature.

High Power Amplifier in a Multi Tone Environment

A multi-tone signal can be characterized by the average and the peak power.
