Elecbee 30MHz-4000MHz Broadband RF Amplifier Module

Elecbee 30MHz–4GHz 40dB Broadband RF Amplifier Module

The Elecbee broadband RF amplifier module provides specified 40dB fixed gain across a wide 30MHz–4GHz operating range. Its compact 25 × 33mm design, nominal 50-ohm signal path and SMA female connectors support integration into RF receivers, laboratory equipment, software-defined radio projects and communication signal-conditioning systems.

40dB Fixed-Gain Amplification

The module is designed to provide high fixed gain for low-level RF signals. Its specified 40dB gain can help compensate for attenuation introduced by cables, filters, splitters and other passive signal-chain components.

A gain-flatness curve and tolerance are not provided. Actual amplification should therefore be evaluated at the intended operating frequency before the module is integrated into a calibrated or precision RF system.

Output Power and Linearity

The amplifier has a specified +20dBm output level at its 1dB compression point. Output P1dB represents the level at which the amplifier’s small-signal gain has compressed by 1dB; it is not a guaranteed continuous output-power rating.

Because the module provides 40dB of gain, excessive input power can cause compression, distortion or receiver overload. Maximum safe RF input power is not specified, so verify the source level and add attenuation where required.

Application Scenarios

• Broadband RF receiver signal chains
• Software-defined radio development
• RF laboratory and test-equipment projects
• Communication and telemetry receivers
• Fixed-gain RF signal conditioning
• Compensation for cable and filter losses

Power and RF Integration

Use a regulated, low-noise 5V DC supply capable of providing the module’s approximately 135mA operating current with suitable margin. Confirm power polarity and terminal assignments before connection.

Connect the module to nominal 50-ohm RF equipment using compatible SMA male cables. High gain amplifies wanted signals, noise and out-of-band interference, so application-specific filtering may be required to prevent overload, unwanted responses or instability.
