超高频 Power Amplifier - 25 Watt (11-99-0000)
The 11-99 power amplifier has two variants to cover the 超高频 frequency bands.
Model 11-99-1000 covers 400-440MHz & model 11-99-2000 covers 450-500MHz
With 4-5 watts input both are designed to deliver 25 Watts output.
Both cover the full switching bandwidth without retuning with 20 Watts minimum output.
The 11-99 is protected against accidental power connection reversal.
The 11-99 power amplifier has two variants to cover the 超高频 frequency bands. 11-99-1000 covers 400-440MHz & 11-99-2000 covers 450-500MHz and with 4-5 watts input both are designed to deliver 25 Watts output. Both cover 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. The 11-99 will operate satisfactorily with down to 1W input power and will give approximately 10 Watts out.
A 2dB 50 Ohm input matching pad allows for connection to a wide range of driving devices without the risk of instability.
In the receive mode it will pass a receive signal with less than 2dB attenuation. The high pass filter is in circuit in the receive mode.
The 3 stage aerial filter attenuates spurious emissions to less than -30dBm.
The 11-99 is protected against accidental power connection reversal.
The green Power LED operates at all times with power connected and the red Transmit LED operates only when the 11-99 is switched to the transmit mode (PTT activated).
