PHA-1H+

RF Amplifiers Overview

The PHA-1H+ is a silicon-based monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. Designed for surface mount applications, it operates within a frequency range of 50 MHz to 6 GHz. The device provides a typical gain of 9.6 dB with a noise figure of 3.4 dB. It requires a single 5 V power supply and draws 132 mA of operating current. Key performance metrics include a P1dB compression point of 22 dBm and an output third-order intercept point (OIP3) of 41 dBm. The component is housed in a compact SOT-89-4 package and supports an operating temperature range from -40°C to +105°C.

RF Amplifiers Procurement Notes

Verify the specific ordering suffix and RoHS compliance status through official Mini-Circuits documentation before procurement. Confirm that the SOT-89-4 footprint matches the target PCB design constraints. Ensure the selected supplier provides valid traceability records for the MMIC lot. Cross-reference the datasheet revision date to guarantee alignment with current electrical specifications and thermal limits.

RF Amplifiers Selection Notes

Select this component when a low-noise, high-gain amplifier is required for frequencies up to 6 GHz. The silicon construction offers a balance between performance and cost compared to GaAs alternatives. Consider the 5 V supply requirement and 132 mA current draw for power budget calculations. Evaluate the 41 dBm OIP3 against system linearity requirements to ensure adequate dynamic range for the intended application environment.

RF Amplifiers Part Context

The PHA-1H+ belongs to the PHA series of RF amplifiers from Mini-Circuits. This series includes various models optimized for different frequency bands and gain levels. The PHA-1H+ specifically targets broadband applications requiring moderate gain and high linearity. It complements other devices in the portfolio such as the LHA-1H+, which utilizes GaAs technology for potentially lower noise figures in similar frequency ranges.

RF Amplifiers Replacement Considerations

The LHA-1H+ serves as a potential alternative, offering similar frequency coverage but utilizing GaAs InGaP technology. Note that the LHA-1H+ has a slightly lower gain of 8.7 dB and a different package type (MCLP-4). Verify pin compatibility and thermal characteristics when substituting, as the silicon-to-GaAs transition may affect biasing requirements and heat dissipation strategies.
