Visão Geral
Description
Key features:
- Frequency range: 6–12 GHz
- Low noise figure: 1.8 dB (typ)
- High gain: 20 dB (typ)
- Single +5V supply operation
- Compact 6-lead LP6 package
The LNA provides excellent linearity (OIP3: +30 dBm) and is ESD-protected, ensuring robust performance in demanding environments. Its small form factor and ease of integration make it suitable for space-constrained designs.
Applications include:
- Military & aerospace systems
- Point-to-point radios
- EW & ECM systems
For detailed specs, refer to the datasheet on Analog Devices' website.
Equivalent
- HMC830LP6GE (similar frequency range, integrated VCO)
- ADF4355-2 (Analog Devices, wider frequency range)
- LMX2594 (Texas Instruments, high-performance synthesizer)
- MAX2870 (Maxim Integrated, broadband PLL/VCO)
These alternatives offer comparable features like low phase noise, integrated VCOs, and programmable output frequencies. Check datasheets for exact specs.
Features
- Frequency Range: 62.5 MHz to 6 GHz
- Ultra-Low Phase Noise: -110 dBc/Hz at 100 kHz offset (1 GHz carrier)
- Fractional-N & Integer-N Modes: Supports flexible frequency synthesis
- Integrated VCO: Eliminates external oscillator needs
- Fast Lock Time: <20 µs typical
- Programmable Output Power: Up to +5 dBm
- SPI Interface: For easy digital control
- Low Power Consumption: 300 mA typical at 5V
- Small 6x6 mm QFN Package: Space-efficient design
Ideal for 5G, radar, test equipment, and wireless comms.
Pinout
Key Functions:

- Integrated VCO: Eliminates external oscillator needs.
- Low Phase Noise: Optimized for high-performance RF systems.
- SPI Interface: For digital control (frequency, power, etc.).
- Differential Output: Supports high-frequency signal generation.
Pin Highlights:
- RF Out (Pins 1, 40): Differential output.
- VCC/GND (Multiple): Power and ground connections.
- SPI (Pins 5–8): Serial control interface.
- LD (Pin 9): Lock detect indicator.
Applications: Radar, test equipment, broadband wireless.
Manufacturer
Analog Devices, founded in 1965 and headquartered in Wilmington, Massachusetts, is a trusted provider of precision analog and digital ICs, often acquired other firms like Hittite Microwave (2014), which originally developed the HMC series. The company emphasizes reliability and cutting-edge performance in its products.
