Product Description

High Sensitivity Reception

The CA4034 HF Switch Matrix has a low noise figure ensuring high system sensitivity, for improved reception of low amplitude signals.

Immune to Strong Interference

The market leading high-linearity characteristics of the CA4034 HF Switch Matrix ensure problem-free operation, even under powerful in-band interference conditions.

Market Leading Isolation

The CA4034 has very high isolation between outputs, minimising undesirable interaction between receivers connected to the CA4034 HF switch matrix, even under extreme mis-match conditions.

Customisable Front End RF Filter

The CA4034 HF Switch Matrix has a customisable front end RF input filter to improve system performance by rejecting unwanted out-of-band interfering signals.

Remote Status Monitoring

To minimise manual maintenance checks, the CA4034 has network capable Built In Test (BITE). The BITE feature enables continuous monitoring of system parameters. Historical trend analysis of BITE data highlights service requirements ahead of failure, maximising system reliability.

Hot Swap, Modular System

The CA4034 modular rack systems are comprised of hot-swap modules. The modular architecture facilitates simple, maintenance and expansion.


The CA4034 range can be customised for specific system requirements.
