CMA-81+
CASE STYLE: DL1721
Product Overview
Mini-Circuits’ CMA-81+ is a wideband monolithic amplifier providing high dynamic range. It uses patented,
Transient Protection Darlington Configuration circuit architecture and is fabricated using InGaP HBT tech-
nology. The amplifier is bonded to a multilayer integrated LTCC substrate, then hermetically sealed under
a controlled Nitrogen atmosphere with gold-plated cover, eutectic Au-Sn solder, and Ni-Pd-Au termination
finish. CMA-series amplifiers have been tested to meet MIL requirements for gross leak, fine leak, thermal
shock, vibration, acceleration, mechanical shock, and HTOL.
Key Features
Feature
Hermetically Sealed
Wideband, DC to 6 GHz
High IP3 vs. DC power consumption
• +41 dBm at 0.1 GHz
• +38 dBm at 1 GHz
Advantages
Ideal for use anywhere long-term reliability adds bottom-line value: high moisture areas,
busy production lines, high-speed distribution centers, heavy industry, outdoor settings,
and unmanned facilities, as well as military applications.
The amplifier covers the primary wireless communications bands including cellular,
PCS, LTE, WiMAX, and satellite IF.
The CMA-81+ matches industry leading IP3 performance relative to device size and
power consumption. The combination of the design and HBT structure provides en-
hanced linearity over a broad frequency range. This feature makes the amplifier ideal
for use in:
• Driver amplifiers for complex waveform upconverter paths
• Drivers in linearized transmit systems
No external matching components
required
Ceramic, hermetic package
CMA-81+ provides input and output return loss from 10.5 to 38 dB up to 6 GHz without
the need for external matching components, simplifying board layouts and saving space.
Low inductance, repeatable performance, outstanding reliability in tough operating condi-
tions, and small size (0.12 x 0.12 x 0.045”)
