We have received during last months many requests to design and supply a simple FrontEnd Limiter based on our 6xBPF-FEL.
The new RX-FEL is already available, a device to help protect receiver front ends from high level signals when operating in the proximity to other transmitters which could damage the receiver. Some examples where it is necessary to incorporate these protectors are multi-transmitter contest stations, Field Day operations or when we have a station very close to ours.
The equipment includes a gas discharger that derives high voltages to ground, a pair of diodes that limit any incoming signal to low levels and that can no longer saturate or damage the preamplifier of the receiver and two baluns to the input and output that ensure the impedance.
The RX-FEL is a RF protector and limiter for your radio receiver or SDR. Installed between the RX antenna and the receiver, it will limited any RF signal and will avoid to damage the receiver because strong signals.
The RX-FEL is a device that will protect the receiver front end from high level signals when operating in the proximity to other transmitters which could damage it. Situations such as multi op contesting, SO2R or Field Day.
- Insertion lost better than 0.4dB in HF (1.8Mhz - 50Mhz)
- VSWR < 1.06:1 (reception)
