RM ITALY LA 250 Series VHF Linear Amplifiers
RM ITALY LA 250 Series VHF linear amplifiers are wideband, compact amplifiers covering 140 to 150 MHz. Available in two models, the only difference is that the LA 250 V includes a pair of cooling fans while the LA 250 does not. These high-power 2-meter amplifiers will provide up to 200 watts FM output. *** Note: Amplifier Color may vary. NOT compatible with DMR and P25 modes LA 250 Series details: * Frequency range: 140 to 150 MHz continuous * Input drive: 1 to 15 watt (maximum). Typically 10 to 12 watts in for 200 watts out * FM output power: 200-watt maximum * Modulation types: SSB, CW, AM, FM, data (switch selectable AM/FM or SSB) * PTT input or RF sense operation * LCD amplifier status screen: -- Input power -- Output power -- SWR -- Heatsink temperature * Internal low-pass filter * Self protection: Reverse polarity, high temperature, load VSWR, and excessive input power * Input VSWR: 1.1 to 1.5:1 * Output VSWR limit: 2.8:1 * SWR power foldback * Optionally cooled version with multispeed fans (LA 250 V) * Supply voltage: 12 to 14Vdc * Maximum DC current: 30A * Internal power fuses: three 10-amp (5x20mm Fast Blow) * Maximum bypass power (amplifier off): 50 watt * Power transistors: 4x Mitsubishi RD70HVF1 Important: Depending upon SWR and input voltage, 200 watts maximum output is typical with 10 to 12 watts input; 15 watts is the maximum input permissible for a low distortion signal. Protection circuits will take the amplifier offline (fault) at about 18 to 20 watts. Running amplifier output at 170 to 180 watts produces a more intelligible signal at virtually the same received level. Note: For additional information, please look at the files under the "Documentation" tab. These RM ITALY LA 250 Series VHF linear amplifiers are perfect for mobile use! You may also want to use them with a 5 watt portable radio or low-power base radio. Order from DX Engineering to give your 2 meter operations a boost!
