15W MAX BOOSTER, with SWR protection

By PCS Electronics - new massively improved model

This wideband no-tune FM broadcast band amplifier unit was developed to supplement the PCI MAX line of fm transmitters, but will work great with any LPFM (low power fm transmitter) on the market. It takes the signal and amplifies it to the full power of 5W / 15W. It can also be used to power other smaller transmitters, up to about 1W of their output power (with engaged attenuator). It does not require tuning as it a wideband no-tune design. It also features a built-in SWR foldback protection that shuts the power off as soon as the SWR reaches critical levels. Unit works from a stabilised DC power supply (12-15V at 4A).

What's cool:
- Power is now linearly adjustable from the outside via the provided potentiometer
- Truly
wideband
- SWR protection circuit
- It CAN be used with PCI MAX cards directly

IMPORTANT NOTE: If you use a 12V fan for cooling, these units typically push 15 - 20W of power.

Here is the manual for the new 5W/15W booster.

Features:
RF Input Power: 25-250mW (selectable hi/lo via jumper)
RF Output Power: 5W (5W model) or 15-20W (15W model – 20W max.)
RF Output Power: Adjustable from 0 to max via potentiometer.
RF output power can be hard-limited internally to 1W max for 5W model only.
Output connector: BNC
Output Impedance: 50 Ohms
Input connector: F (designed to match easily with the PCI MAX transmitters)
Input Impedance: 50 Ohms
Frequency Range: 86-108MHz
Spurious/Harmonic rejection: Harmonics: > 50dB min.
Built in SWR fold-back protection (with a warning LED)
Available points for measuring power and SWR inside the
amplifier (built-in SWR meter)
Built-in stabilized DC (12-15V/1A) power supply for other projects or PCI MAX ULTRA
Power Supply: 13.8V/5A or mains (110-240V/ 50-60Hz)
Dimensions:
PCB board: 145x110mm, double-sided professional PCB
Enclosure: 210x115x40mm, black anodized aluminum
