Description

6000 watt low pass filter with or without directional coupler.

Assembled and tested low pass filter board, ready to be installed. Heavy duty design, large and sturdy. This board can be mounted to the floor of an amplifier chassis or inside a separate enclosure. Airflow and bolting to suitable heatsink are required at top power levels. Surface mount construction makes installation easy. There is no need for PCB spacers because the inductor leads to not pass through the PCB.

Technical specifications:
– 86-108MHz
– Impedance: 50 ohms
– 9th order Chebyshev typology.
– Ultra low loss PTFE PCB; tightly controlled dielectric constant.
– large awg inductors
– 0.1 dB insertion loss maximum
– -25dB return loss maximum
– -50dB rejection at 176MHz. That’s the 1st harmonic of 88MHz.
– Measures 100,33mm x 318,77mm (12.55″ x 3.95″ x 1.5″), needs clearance of about 2cm (0.75″) above coils to prevent coupling
– Must be installed on metal heatsink for cooling, nylon screws must be used to prevent arcing.
– Filter is bi-directional, input and output can be exchanged.

Note: Use PTFE coax/semi-rigid to make connections, suitable cables are here.  0.250 inch semi-flexible hand-bendable 50ohm cable is a good fit.

Important: Keep leads very short, every millimeter counts!
