PHA-13HLN+ SMT MMIC, Low Noise, Medium Power, Linear, pHEMT Amplifier

Functions

1. Extreme Ultra-Wideband Operation: A defining feature of the PHA-13HLN+ is its exceptional frequency coverage, spanning from 10 MHz to 13 GHz. This extensive bandwidth enables it to amplify signals across virtually all key RF and microwave bands (HF, VHF, UHF, L-band, S-band, C-band, X-band, and lower Ku-band), eliminating the need for multiple narrowband amplifiers and simplifying multi-band system design.
2. Superior Low-Noise Performance: It delivers outstanding low-noise characteristics, with a typical noise figure (NF) as low as 1.5 dB at 1 GHz and remaining below 3 dB across most of its operating band (e.g., ~2.5 dB at 6 GHz, ~3 dB at 12 GHz). This minimizes noise interference when amplifying weak incoming signals, a critical attribute for boosting the signal-to-noise ratio (SNR) and enhancing the sensitivity of receiver systems.
3. High and Flat Gain Response: The amplifier provides consistent, high fixed gain of 18 dB ± 2 dB across its entire 10 MHz–13 GHz bandwidth. The flat gain profile ensures uniform signal amplification across all frequency bands, avoiding signal distortion or attenuation that could degrade system performance in wideband applications.
4. Excellent Linearity: It offers robust linear performance, characterized by a typical 1-dB compression point (P1dB) of +17 dBm and a third-order intercept point (IP3) of +28 dBm. This linearity prevents signal distortion even when handling moderate input power levels, making it suitable for both sensitive receiver front-ends and low-to-moderate power transmit paths.
5. Simple Single-Supply Operation: The PHA-13HLN+ operates from a single positive DC supply voltage of +5V, with a low quiescent current of approximately 60 mA. This simplifies power supply design, reduces energy consumption, and enhances compatibility with both benchtop instruments and embedded, power-constrained systems.
6. Compact, High-Reliability Package: Encased in a compact 8-lead QFN (Quad Flat No-Lead) surface-mount package (3mm x 3mm), the amplifier occupies minimal printed circuit board (PCB) space—ideal for dense RF modules and miniaturized electronic devices. The package is compatible with standard reflow soldering processes, supporting high-volume manufacturing while ensuring mechanical and environmental ruggedness.
7. Integrated Input/Output Matching: It features internal 50Ω input and output impedance matching, eliminating the need for complex external matching networks. This simplifies PCB layout, reduces design time, and ensures optimal performance across the entire frequency band when connected to standard 50Ω RF systems.
