1.42GHz 1420MHz RF Power Amplifier Module 15W Output 40dB Gain CNC Cavity Microwave Amplifier Module for High-Frequency Applications

High-performance 1420 MHz RF power amplifier in a precision CNC-machined aluminium cavity — engineered for demanding microwave applications requiring clean, stable amplification.

Key Specifications

• Center frequency: 1420 MHz (1.42 GHz)
• Output power: 15 W (41.8 dBm)
• Gain: 40 dB
• Input power: 0 dBm typical (1 mW drive)
• Supply voltage: 12 V DC, ~3.5 A
• Impedance: 50 Ω (SMA connectors)
• Spurious / harmonic suppression: >40 dBc

Construction

• CNC-machined aluminium cavity housing — excellent RF shielding
• SMA female input / output connectors
• Integrated bias circuit and DC blocking capacitors
• Mounting holes for heatsink or chassis installation

Applications

• Amateur radio (L-band EME, AO-40 uplink)
• Radio astronomy (hydrogen line 1420.405 MHz)
• RFID / UHF test setups
• Wireless link experimentation and range extension

Always connect a 50 Ω load before applying RF power. Proper heatsinking is mandatory — module can reach 70 °C at full output. Check local regulations before transmitting.
