GVA-82+: LTE Performance vs Output Power
Mini-Circuits GVA-82+ high dynamic range MMIC amplifier is designed specifically for applications which require high linear performance, particularly wideband, advanced digital communications systems such as LTE which require excellent ACLR suppression and low EVM.
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. To use one of these graphs it is necessary to know the junction temperature of the particular device. This article provides guidance for determining the junction temperature.

This article reviews noise theory & measurements and S-parameter measurements used to characterize transistors and amplifiers at Modelithics, Inc.
UMTS (WCDMA) Performance vs. Output Power (TAMP-242GLN+)
Mini-Circuits TAMP-242GLN+ ultra-low noise drop-in amplifier module is an ideal low noise amplifier for use in UMTS (WCDMA) base station or tower mounted low noise applications. The TAMP-242GLN+ provides an optimized combination of critical performance: low noise/high dynamic range/input & output match/unconditional stability.
Transient Protection of Darlington Gain Block Amplifiers
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.
PMA-545+: LTE Performance vs. Output Power
Mini-Circuits PMA-545+ high dynamic range and super low noise MMIC amplifier is designed specifically for applications which require high linear performance, particularly wideband, advanced digital communications systems such as LTE which require excellent ACLR suppression and low EVM.
MMIC Test Boards: Instructions for Use
Mini-Circuits manufactures a wide range of 4-pin MMIC surface-mount and drop-in amplifiers. A family of test boards for evaluating these devices has been designed to make them easy to use by customers.
PGA-105+: Stabilizing Network
The PGA-105+ is a 15 dB gain monolithic amplifier for the 40-2600 MHz range with excellent gain flatness and a high dynamic range (1 dB compression point: 19.3 dBm @ 2 GHz).
Power Supply Transient Protection for MNA and VNA Amplifiers
Shorting of the DC voltage terminal of a MMIC amplifier to ground while DC power is connected can cause permanent damage to the amplifier. This can occur, for example, in a test setup where the amplifier is in a fixture with clip leads for the DC connections; the clips are accidentally moved and they momentarily short the DC and ground terminals together.
Biasing of Constant Current MMIC Amplifiers (e.g. ERA Series)
The Mini-Circuits family of microwave monolithic integrated circuit (MMIC) Darlington amplifiers offers the RF designer multi-stage performance in packages that look like a discrete transistor. Included in this family are the model prefixes to which the biasing considerations in this article apply: ERA, Gali, LEE, MAR, MAV, RAM, and VAM.
