システック リサーチ インク List of Products and Services

Cystec Research Inc. is the only manufacturer in Japan specializing in frequency synthesizers, PLOs, and PDROs up to 55GHz. Since its establishment, the company has dedicated itself to the research, development, and supply of digital frequency synthesizers in the RF and microwave bands for the fields of electronic communications, broadcasting, and measurement instruments, and has received various public business support such as special loans and subsidies from Kanagawa Prefecture. As a result, over 20,000 synthesizers have already been manufactured and shipped. Particularly with the start of terrestrial digital TV broadcasting in our country, a signal source with extremely low phase noise is essential for accurately transmitting the modulation scheme, OFDM signals. Our company is also the only manufacturer specializing in supplying synthesizers and phase-locked oscillators to TV broadcasting stations, TV relay stations (SFN, MFN), microwave links, and FPUs in this field.

The microwave signal source "PLSS-DD-133-000" is a compact dual-loop PDRD (Phase-Locked DRO). It phase-locks to an external reference frequency input to the built-in 100MHz band VCXO (ultra-low phase noise -120dBc/Hz at 100Hz offset). Therefore, the phase noise level of the PDRD's loop, which phase-locks this 100MHz band VCXO, is not directly affected by the external reference input. It can output a low phase noise microwave signal without being influenced by the C/N level of the external reference input. For more details, please download the catalog.

The microwave signal source "PLSS-SC-133-000" is a compact and lightweight single-loop PDRD (Phase-Locked DRO) designed for operation. It synchronizes with an external reference input in the 100MHz band and outputs a microwave signal with low phase noise (8-3GHz). The phase noise characteristics are determined by the C/N of the external reference input, calculated as C/N = C/N(Ref.) + (20log fo/fr + 3). This phase-locked DRO employs the latest MMICs, achieving high RF output and low power consumption (below 2W). For more details, please download the catalog.

The microwave signal source "PLSS-SC-9601-000 (V1)" is a low-cost, single-loop phase-locked DRO designed in a compact size. It outputs a microwave signal at fo = 9600 MHz, phase-locked to an external reference signal (fr) in the range of 50 to 100 MHz. The phase noise of the output signal fo within the loop bandwidth (C/N) is calculated using C/N(dBc/Hz) = -C/N(dBc/Hz) of fr + 20log(fo/fr). Therefore, for a microwave signal with low phase noise, we recommend using a crystal oscillator with extremely low phase noise, such as a -160 to -170 dBc/Hz sc-Cut OCXO or TCXO.
