Review WATKINS JOHNSON Tunable Demodulator

The WJ-9477 Watkins Johnson Tunable Demodulator is a high-performance, versatile signal processing device designed for use in various communication systems. This demodulator offers exceptional tuning flexibility, with a wide frequency range of 100 kHz to 4 GHz, making it suitable for a broad array of applications.

The WJ-9477 features a high-quality, phase-locked loop (PLL) controlled local oscillator (LO) that provides precise frequency tuning. The LO has a fixed frequency of 10 MHz, but its output can be directly frequency-multiplied or externally frequency-synthesized, providing further tuning options. The demodulator also includes a built-in digital phase detector, which ensures precise and stable LO phase locking, even in the presence of strong phase noise.

The WJ-9477 supports several demodulation formats, including AM, FM, and FM-DR, making it ideal for applications requiring analog modulation decoding. It features a high-resolution, 12-bit analog-to-digital converter (ADC) with a sampling rate of up to 10 MS/s, ensuring accurate signal processing and high-fidelity demodulation.

The demodulator's input and output interfaces are designed to be compatible with various signal sources and sinks. It features a high-speed, low-noise, RF input with a 50 impedance, and a high-speed, low-distortion, and low-noise digital output. The demodulator also includes a built-in 12-bit digital-to-analog converter (DAC) for direct signal output.

The WJ-9477 is housed in a compact, ruggedized enclosure designed to withstand harsh environmental conditions. It is powered by a 12 V DC input, and its power consumption is minimal, making it an energy-efficient solution for portable and battery-powered applications.

In conclusion, the WJ-9477 Watkins Johnson Tunable Demodulator is a powerful and versatile signal processing device that offers exceptional tuning flexibility, high-quality demodulation, and robust construction. Its wide frequency range, support for various demodulation formats, and compatibility with various input and output interfaces make it an ideal solution for a broad range of communication systems.
