Toptek Communications PA-350V VHF 135-165 MHz 350W Power Amplifiers
Toptek Communications PA-350V VHF 135-165 MHz 350W Power Amplifiers are advanced and versatile high-power linear amplifiers designed for Amateur Radio 2 Meter FM, SSB and CW operations and Commercial VHF. A large, easy-to-read green backlit Alphanumeric LCD provides simultaneous digital input power, output power, SWR readings. Front panel button actions and specialized, user-defined function readouts and menu selections are displayed, including incremental 100, 200, 300 and 350W power output settings. This VHF amplifier* delivers approximately 300 watts output with only 5 watts input from an HT or 350 watts maximum output with a VHF mobile. The PA-350V has two selectable input ranges, Low 15W max and High 30W max, achieving 350 watts output with either 10 watts input or 15 to 25 watts input, to accommodate almost any VHF transceiver. Multiple protection circuits, a Receive Low Noise Amplifier (LNA) with bandpass filter, RF sense or PTT keying (required for SSB/CW) and thermostatically controlled fans are some of the great features of this top-of-the-line Toptek amplifier. True 50 ohm Type-N RF connectors maintain the highest efficiency to the feedline and antenna. NOT compatible with DMR and P25 modes NOTE: Rear panel accessory jack (4-pin mini-DIN) is provided for the accessory REMOTE Control Panel, TEK-REMOTE. *Requires 13.8 VDC @ 50A max. (External power supply not included).

Toptek Communications PA-180V VHF 138-174 MHz 180W Power Amplifiers
Toptek Communications PA-180V VHF 138-174 MHz 180W Power Amplifiers are very stable Solid State VHF linear amplifiers designed for Amateur Radio 2 Meter FM, SSB and CW operations and Commercial communications. Dual MOSFET push-pull PAs provide full RF output of 180 watts with only 5 watts input, making this amplifier* useful for both handheld and compatible mobile VHF transceivers. Mode, RX preamp, SWR meter and Power Output Settings of 60, 100, 140 and 180 watts are front panel selectable. The front panel multi-color 8 LED string serves to indicate output power settings, output power, SWR and Error. A unique shroud enables the oversize fan to quietly cool this compact amplifier for safe long-term operation at full power. Multiple protection circuits, a 21dB Receive Low Noise Amplifier (LNA), RF sense or PTT keying (required for SSB/CW) and thermostatically controlled fan are some of the great features of this Toptek VHF amplifier. True 50 ohm Type-N RF connectors maintain the highest efficiency to the feedline and the antenna. NOT compatible with DMR and P25 modes. *Requires 13.8 VDC @ 30A max. (External power supply not included).

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!
