Z-COMM Unveils High-Performance 2.5 GHz Phase-Locked Oscillator for Critical RF Applications
June 26, 2025
Z-Communications Inc., a leading innovator in RF and microwave components, has announced the release of its latest Phase-Locked Oscillator (PLO)—the FSG2500LX, expanding the company’s renowned FSG series. This new model delivers ultra-low phase noise and robust performance at a fixed 2.5 GHz output frequency, making it ideal for defense, SATCOM, radar systems, and precision test & measurement platforms.
Engineered for Precision, Built for Harsh Environments
At the heart of the FSG2500LX is its best-in-class phase noise performance:
- -112 dBc/Hz @ 1 kHz & 10 kHz offset
- -118 dBc/Hz @ 100 kHz
- -150 dBc/Hz @ 1 MHz
- -161 dBc/Hz @ 10 MHz
This exceptional spectral purity ensures minimal signal distortion, reduced jitter, and reliable performance in systems where timing accuracy and signal clarity are critical.
Key Features at a Glance:
- Frequency Output: 2.5 GHz (fixed)
- Output Power: 17–21 dBm (typical 19 dBm)
- Impedance: 50 ohms
- Reference Input: 100 MHz external or internal
- Control Signals: 3.3 V PSYNC (phase sync) and lock detect output
- Power Supply: 13–18 V DC, 210 mA typical
- Startup Time: 15 ms
- Operating Temperature: -40°C to +85°C
- Enclosure: Rugged, all-metal housing for durability in field or lab environments
“The FSG2500LX brings together spectral purity, fast response, and rugged reliability—ideal for engineers integrating high-performance PLOs into complex RF systems,” said a spokesperson for Z-COMM.
Ideal for Mission-Critical Systems
Whether used in radar, military communications, SATCOM terminals, or automated test equipment, the FSG2500LX offers the dependability and electrical performance needed for high-stakes RF design. With flexible synchronization features and a rapid power-up cycle, it’s engineered to meet the needs of real-time systems.
Its compact footprint and low power consumption also make it a smart choice for portable or embedded platforms, where board space and efficiency are at a premium.
