Engineering-focused RF product descriptions and system patterns for terrestrial, satellite and studio-to-transmitter media delivery.
Broadcasting and media distribution depend on RF subsystems at every link: studio output, STL/ENG links, high-power transmitters, satellite uplinks and receiver monitoring. This page catalogues the RF products, subsystems and engineering considerations required to design, deploy and maintain resilient media networks for TV, radio and live streaming.
SSPA (GaN-based solid-state power amplifiers), TWT (travelling wave tube) transmitters and hybrid transmitters for VHF/UHF/SHF broadcast. Key features: output power stages, cooling, redundant exciter chains, spectral purity and regulatory masks.
Digital exciters and modulators supporting DVB-T2, ATSC, DAB, FM/AM, ISDB-T with integrated encoders, FEC, COFDM and IQ baseband interfaces. Provide modulation depth, pilot carriers and spectral shaping.
RF upconverters for satellite uplinks (L-band → Ku/Ka-band), and downconverters for receive chains. Include LO stability, spurious suppression and IF/RF filtering.
LNAs for satellite receive dishes, STL receive antennas and monitoring probes. Key specs: noise figure, gain flatness, IP3 and built-in lightning/surge protection.
Broadcast panel antennas, high-gain parabolic dishes, sector antennas for SFN sites, FM broadcast arrays, and precision feeds/waveguide assemblies. Include polarization, VSWR, gain patterns and PCV data.
Tower combiners for multiple transmitters, cavity/SAW/ceramic filters, harmonic traps, duplexers and diplexers to manage shared antenna systems and suppress spurious emissions.
Hybrid combiner networks, antenna changeover switches, directional couplers for monitoring, RF loads and redundant PA chains for N+1 availability and graceful degradation.
Site monitoring receivers, spectrum analyzers, RF power meters, VSWR monitors, remote RF probes and telemetry for on-site and NOC-level health dashboards.
Waveguide runs, coaxial trunk lines, low-loss jumpers, precision connectors (7-16, N, SMA), isolators, circulators and attenuators for insertion-loss control and isolation.
RF microwave STL links (licensed bands), VSAT/IP hybrid uplinks, ENG microwave packs for remote production — include link budget planning, latency and channel coding.
RF-over-fiber heads for remote transmitter sites, optical transceivers, and remote monitoring interfaces enabling centralized exciter control and localized high-power amplification.
RF site bonding, surge arrestors, lightning protection for antenna systems and PA protection modules integrated with station power and telemetry.
Exciter + SSPA/TWT transmitter + combiner + antenna system + RF monitoring + site protection. Delivery includes link planning and acceptance testing.
Upconverter, high-power SSPA, parabolic dish & feed, downconverter and LNA receive chain, monitoring and spectrum compliance report.
Licensed microwave radios or RF-over-fiber headend, latency-optimized modulation, and N+1 redundancy for live contribution paths.
Site spectrum analyzer, VSWR/power probes, remote telemetry agent, automated sweep reports and alerting integration for NOC.
All RF transmission and uplink activities must comply with local spectrum regulations and licensing. Transmitter installations must be carried out by certified personnel and follow safety, grounding and RF exposure guidelines.
