RM ITALY LA435 Wideband UHF Amplifiers
RM ITALY LA435 Wideband UHF Amplifiers are very compact linear units that cover from 405 to 480 MHz. They are ideally suited to low power handheld transceivers, requiring input drive from 1 watt to a maximum of 5 watts, delivering a nominal 60 watts of full output power, 70 watts PEP maximum. The LA435 amplifier features automatic "RF Sense" switching between RX and TX and it bypasses when it is switched off for low power operation. The SSB mode adds a small transmit-receive delay for smoother voice operation. The rear panel European-style removable DC power connector cable facilitates easy installation with a user supplied DC power cable fused for 15A at 13.8 VDC. The DC power cable to the mobile battery or power supply should be as short as possible. Use of a minimal length of low-loss 50 ohm coaxial cable to the appropriate UHF antenna is recommended. The LA-435 features Type-N input and output RF connectors to minimize losses. Actual output power depends on coaxial cable and antenna SWR as well as frequency of use. A graph in the manual illustrates the relationship between input and output power at 435 MHz. NOT compatible with DMR and P25 modes.
