RM Italy LA435 amplifier 405 - 480 MHz, 70 W

The LA435 from RM Italy is a compact, broadband power amplifier for the 70 cm UHF band. It covers the entire frequency range from 405 to 480 MHz without any gaps. 

The output power is nominally 60W (70W max). 

Input power from 1W to 5W max, ideally suited for low power handheld radios. Output power depends on both input power and frequency used. The diagram illustrates the relationship between these two parameters. 

The amplifier has automatic switching between RX and TX. 

The power cable for the amplifier should be kept as short as possible and be less than 3 m long. In case of mobile installation, it is recommended to connect the power cable directly to the vehicle battery. A fuse can be installed at this point to protect against short circuits. 12 to 15A is sufficient as the amplifier is internally fused. 

The amplifier can be left in the circuit when powered off, and the RTX can be operated normally at low power.  

When the SSB/FM switch is set to "SSB", a small delay is added before switching back to "RX" after a transmission. In SSB, this prevents the amplifier's RX/TX relay from constantly switching between "receive" and "transmit" during pauses in speech, since there is no RF carrier to hold the relay in the open state. In FM and AM modes this is not necessary and the switch position can be set to "FM".

Power supply: 12 - 15 V DC, max. 15 A.
