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.
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.
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.
