Amphenol Military & Aerospace (AMAO) RF Amplifiers comprise a family of high‑performance microwave amplifier assemblies used across radar, satellite communications, telemetry, and instrumentation systems. The range aggregates multiple sub‑families such as low noise, cryogenic, log, and amplifier‑switch assemblies produced through the Narda‑MITEQ engineering heritage.

Performance and Design

• Frequency coverage across 0.1 GHz to 40 GHz depending on model, including octave and multi‑octave Band UHF through Ka‑band variants.
• Output power levels typically from +10 dBm to +25 dBm with gain options of approximately 20 – 40 dB.
• Optimized noise figures down to the sub‑dB level for low‑noise front‑end architectures.
• 50 Ω input and output impedance ensuring broadband impedance control and low VSWR performance.
• Nominal +15 VDC operation with internal regulation across standard AMAO amplifier modules.

Mechanical and Environmental Features

• Hermetically sealed and internally regulated constructions available for military and aerospace qualification.
• Operating temperature range generally −55 °C to +85 °C with survival storage down to −65 °C and up to +125 °C.
• Ruggedized housings designed to endure vibration, shock, and humidity per MIL‑STD environmental norms.
• RoHS‑compliant materials and optional connector styles including SMA, K, N‑Type, TNC, and waveguide interfaces.

Variants and Customization

• Low Noise Amplifiers (LNA): wideband, unconditionally stable front‑end amplifiers for high‑sensitivity receivers.
• Cryogenic Amplifiers: optimized for ultra‑low‑temperature operation in scientific and quantum systems.
• Log Amplifiers: amplitude‑proportional detectors used in instrumentation and signal‑monitoring channels.
• Amplifier Switch Assemblies: integrated gain and routing modules for complex RF paths or test networks.
• Custom gain slope correction, limiter protection, and phase/gain tracking features available on request.

Applications

• Radar receivers and front‑end modules
• Satellite communication uplink and downlink systems
• Electronic warfare and telemetry equipment
• Test instrumentation and laboratory R&D installations
• Transceiver subassemblies in military and aerospace platforms

These amplifier assemblies provide a modular foundation for both commercial and defense high‑frequency systems, combining configurable performance with proven environmental durability.
