11-99-0000 UHF 25W Power Amplifier

  • Operating over a frequency range of 400-440MHz and 450-500MHz, the Salcom 11-99 Power Amplifier provides up to 25 Watts of power from a 4 Watt input.

    The 11-99 covers the full switching bandwidth without retuning with 20 Watts minimum output.

    The power sense operates with a minimum of 1 Watt input and switches both the power and aerial relays. It will operate satisfactorily with as little as 1 Watt input power, where it will give approximately 10 Watts out.

    A 2dB 50Ω input matching pad allows for connection to a wide range of driving devices without the risk of instability.

    In the receive mode, the 11-99 will pass a receive signal with less than 2dB attenuation. The high pass filter is in circuit in the receive mode.

    The three stage aerial filter attenuates spurious emissions to less than -30dBm. The 11-99 is protected against accidental power connection reversal.

    The green LED operates at all times with the power connected, and the red transmit LED operates only when the 11-99 is switched to the transmit mode.
