Coollaboratory Liquid Pro is the first thermal compound that consists of 100% liquid metal alloy. It is liquid at room temperature (like mercury), but it is absolutly nontoxic and has a high moistening ability for several materials apart from aluminum. The Coollaboratory Liquid Pro is especially recommended for nickel-plated copper.

Tandem match TX-RX unit for LDMOS MOSFET tube amplifier 100-2400W





The SWR sensor 2 pcs
Cable - RG142
Toroid - Micrometalls FT82-43
Schottky diode 1N5711
1.8-54 MHz
Power - 100W - 3 KW
TX-RX unit is intended to provide the switching of amplifier between receive and transmit modes.
Input signal is PTT line from transceiver.
When PTT input goes low, the relays directs the signal from transceiver to PA input and from PA output to antenna. When PTT is high (RX mode) the antenna is connected directly to transceiver.
The second tandem match is used as a high SWR detector with incorrect, spontaneous switching, failure of the LPF.
More than 50% of the transistor amplifier failure occurs due to incorrect or spontaneous switching of the LPF.
When there is a spontaneous switching of the LPF, which depends on the interference to the band decoder, transceiver, computer, etc., then the combustion of the transistor happens. The leads disappear right after that. You can not find the problem.
You need to have control over the state of the LPF.
Attention!
This protective device is designed to NOT work with a LPF-diplexer.

Smart High Current DC Switch with protection triggers for power amplifiers.





The application of this DC switch is to gate the power supply current to solid-state amplifier and safely disconnect it in case of emergency.
Features:
• Overload protection
• Current limitation
• Short circuit protection
• Over temperature protection
• Over voltage protection
• Diagnostic feedback with load current sense
• Operating voltage 5 – 58 VDC
• Operating current 44 A max
• On-state resistance 7.2 mΩ
To allow the switch to be disabled by an emergency signal, 3 protection triggers are added to board:
• high VSWR protector to disconnect the amplifier from power supply if SWR rises higher than preset
level 2.0:1 (may be varied by user) . Forward and reflected wave voltages from external directional
coupler must be provided to determine the VSWR independent of power level.
• output power excess protector to disconnect the amplifier if output power is more than preset level. Fine
threshold tuning from 150 up to 1500W with one BTS660P and 150 up to 2500W with two BTS660P in
parallel.
• DC current excess protector to disconnect the amplifier if current consumption is more than preset level.
Fine threshold tuning from 20 up to 40A with one BTS660P and 40 up to 80A with two BTS660P in
parallel.

Red LED shows which trigger is on. Power off and then on to reset device.

The onboard current sensor provides about +1VDC at 30 Amps for external current meter. Meter impedance must be at least 10 KOhm. BTS660P has a min switch-off time as low as 30 microseconds, so fast enough to protect the amplifier in case of emergency.
Two BTS660P units may be installed on PCB to provide the current up to 2500 W amplifiers without additional heatsinks.

PEP/AVG LCD SWR/PWR meter indicator up to 2400W





The device is designed to display on the LCD alphanumeric display the values ​​of the forward power and VSWR . For this purpose it should be connected to the directional coupler ( SWR bridge) of any design, say Tandem-match .
Thanks to peak detector on operational amplifier, this meter is capable to measure the PEP (peak envelope power) as well as average. The jumper on PCB is pre-set to PEP position, but it could be replaced by external selector to switch between PEP and AVG modes.
The forward voltage must be applied to the input port F, reflected to input port R.
Power supply voltage is +7.5...+15 volts.
Minimum voltage from directional coupler (SWR bridge) +2.55V

For proper operation the device requires calibration. Calibrate the Power Meter readout by trimmer FWR with reference meter. Calibrate the SWR readout by REV trimmer with reference meter connected in series to the antenna or using the dummy load with known resistance , 100 ohms for example. In this case, VSWR have to be set to 2.0:1 .
