Procom UK Systems, the distributer for Procom A/S, the Danish designer and manufacturer of antennas, filters and combining equipment, has recently launched new components for use with distributed antenna systems (DAS).
First up is a new tapper - the PRO-TAP 380-2700 - a multiband tapper covering the 380-2700MHz band. It provides ‘excellent high power performance coupled with low insertion loss over the entire frequency range’ according to the company.
Power tappers are devices that tap off a portion of the signal while allowing the rest of the signal to pass through with a minimum of loss. Tappers operate similar to directional couplers, but without the directivity and have relatively broad bandwidths. Tappers are used where small coupling values are not required.
Key features: PRO-TAP 380-2700
- 500W power
- 6, 10 and 20 dB coupling
- Low VSWR on input/output ports.
- No directivity.
- Coupled port must be terminated.
- Wide bandwidth.
- High Power.
- Accurate coupling values.
Procom has also introduced a new range of directional couplers, which provide isolation between outputs along with directivity. Couplers are used when small coupling values and isolation between outputs is required.
Bands covered include: 80-140, 112-200, 200-300, 300-400, 380-430, 380-470, 300-1000 and 800-2500MHz.
Key features: Procom directional coupler
- Coupling 10, 20, 30dB.
- Low VSWR on all ports.
- Isolation between outputs.
- Moderate bandwidth.
- High Power.
- Rippling in coupling value over frequency.
