Commercial Analog CATV Modulators: Precision SAW Filtering & Cost-Effective Coaxial Distribution

Converting multi-channel CVBS/AV baseband sources into broadcast-grade RF analog carriers with hardware-level SAW filtering. Engineered for high-density 16-in-1 headend racks, strict adjacent-channel transmission, and zero-STB legacy television networks.

Broadcast-Grade SAW Filtering & High C/N Adjacent-Channel Operation

Engineered with broadcast-grade Surface Acoustic Wave (SAW) filtering and vestigial sideband (VSB) filtering circuits, SOUKA analog modulators deliver outstanding out-of-band suppression and an ultra-high Carrier-to-Noise ratio (C/N ≥ 60 dB). This precise RF circuit design enables stable adjacent-channel transmission without visual ghosting, diagonal herringbone distortion, or audio buzz across continuous frequency allocations, maximizing usable spectrum over legacy coaxial networks.

Global Standard Versatility & Agile RF Output Power (90 to 105 dBµV)

SOUKA analog modulators provide agile frequency synthesis across 47 to 862 MHz (VHF/UHF full-band coverage), offering firmware compatibility with global analog television standards including PAL-B/G/D/K/I, NTSC-M, and SECAM-D/K. The integrated RF power amplifier delivers an adjustable output level from 90 to 105 dBµV (with 0–20 dB continuously variable attenuation), directly driving clear analog signals across long 75-ohm coaxial trunk runs (RG6/RG11) without requiring external pre-amplifiers.

High-Density 16-in-1 Modular Chassis & Zero-STB Retrofit Economics

Designed for centralized headends, SOUKA provides high-density 4U 16-in-1 / 24-in-1 rackmount chassis featuring modular hot-swappable cards, dual active cooling fans, and high-efficiency commercial power supplies. By utilizing existing coaxial cabling, televisions with built-in analog tuners receive multi-channel video directly with zero external set-top boxes (Zero STB) and sub-10ms transmission latency, slashing renovation CapEx and eliminating remote-control maintenance across legacy hotels, schools, and hospitals.
