RF Passive Components
The distribution and combining hardware at the coverage-system edge: splitting, coupling, combining, duplexing, filtering and connection — supplied from the same source as the head-end, avoiding impedance and insertion-loss problems from mixing vendors.
Power splitting & coupling
Power divider / splitter
2 / 3 / 4 / 6-way options in cavity and microstrip construction; selected against the branch insertion-loss budget.
Directional coupler
6 / 10 / 15 / 20 dB coupling for branch sampling and power distribution.
3 dB hybrid
Equal power split with high isolation between outputs; used for combining and balanced distribution.
Power tapper
For DAS branch distribution, replacing cascaded splitters to hold cumulative loss down.
Combining & duplexing
Combiner / hybrid combiner
Merges multiple signal paths onto one antenna — the reverse function of a splitter.
Duplexer
Transmit and receive on a shared antenna; selected by duplex spacing and bandwidth.
Multiplexer
Several bands on one antenna for multi-network convergence.
POI multi-system platform
Combines multiple operators or systems into one distribution system — standard for metro, airports and large venues.
Filtering & protection
Cavity filter
Band-pass, band-stop, high-pass and low-pass types to suppress out-of-band and adjacent-channel interference.
Isolator / circulator
Protects the amplifier and suppresses reflections; the circulator serves shared transmit/receive paths.
Surge arrestor
Required at outdoor antenna and feeder entries; mandatory for lightning-prone and tower-top sites.
RF dummy load
For power testing and burn-in, 50 Ω matched, available across power ratings.
RF attenuator
Link level adjustment and commissioning, in fixed and variable forms.
Connectors & cable
RF connectors
N / SMA / BNC / 7-16 interfaces, including male, female and adaptors.
RF coaxial cable
1/2″ and 7/8″ feeder and assemblies, chosen by loss and installation conditions.
Jumper & feeder assembly
Cut to site length with terminations fitted; insertion loss measured before dispatch.
- Uplink and downlink signal extractors are directional by design and cannot be swapped.
- A signal extractor cannot be replaced by an ordinary directional coupler — isolation and phase relationships differ.
- Every component is measured for insertion loss and VSWR before dispatch; test records ship with the goods.
- Final interfaces, bands and power ratings follow the contract configuration list.
