High Frequency (RF) Relays

High frequency (RF) relays, also known as radio frequency (RF) relays, are specialized relays designed to switch signals in the range of frequencies from several kilohertz (KHz) up to several gigahertz (GHz). RF relays balance the need to provide isolation between the high frequency circuit and the control circuit, a requirement common to both analogue and digital electronics. G6ZK-1P DC5 is a typical example of RF relays.

G6ZK-1P DC5 Application Field and Working Principle

G6ZK-1P DC5 is a radio frequency (RF) SPDT switching relay designed for applications requiring a narrower frequency range. It is specified for use in a wide range of communication equipment, including spectrum analyzers, frequency counters, communication systems, VHF, UHF, cellular and PCS base stations, modems and receivers.

The typical PCB-mounted G6ZK-1P DC5 RF relay is composed of two primary parts. The first part is the RF terminal and the second part is the DC power terminal. The RF terminal of the relay consists of several components, including the moving armature, stationary contacts, earth plate, carry mechanism and control coils. The DC power terminal is composed of the switching coil and its associated DC power transistor CMOS switch.

The main principle of -G6ZK-1P DC5 is the same as that for any other RF SPDT switching relay. In normal operation, the RF terminals (incoming and outgoing signals) are connected in series. When power is applied, the relay’s switching coil energizes and causes the armature to move to the “on” position. This switches the contact between the incoming and outgoing signals, allowing the outgoing signal to pass through the relay to the receiver. When the relay’s power is turned off, the armature moves to the “off” position and the contacts are opened, thus isolating the incoming and outgoing signals.

Therefore, G6ZK-1P DC5 can be used in various applications for signal control, conversion and protection. It provides a very reliable and low-friction switching operation, enabling it to switch signals in the range of frequencies from several KHz up to several GHz. The specifications of G6ZK-1P DC5 are provided in the table, showing its excellent operation performance in line with its outstanding design.
