KIT 144-148 MHz protection LDMOS amplifier LPF 1000W tandem match couppler PTT
PTT board - TX-RX unit for 144-148 MHz. Directivity of 22 dB from 26 dB 70 to 146 MHz.
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. Diagnostic feedback with load current sense. Operating voltage 5 58 VDC.To allow the switch to be disabled by an emergency signal, 3 protection triggers are added to board. 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. Threshold tuning from 150 up to 1500W with one BTS660P and 150 up to 2500W with two BTS660P in. 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. Red LED shows which trigger is on.
