RF Switches

RF Switches

ADI offers a wide range of high performance RF switches that are ideal for instrumentation, communications, military and aerospace applications. Manufactured in GaAs and Silicon (SOI) processes, RF switches feature higher power handling, better linearity and wider frequency band of operation compared to their CMOS counterparts. ADI’s new Silicon (SOI) RF switches offer unmatched performance in compact SMT form, which attains superior insertion loss, improved isolation, wider bandwidth and faster switching/settling times than any other solution.

Bypass, Diversity, Matrix, and Transfer Switches

Analog Devices positive control transfer switches and switch matrix products are used in applications including test instrumentation; DBS LNBs and multiswitches; military radios, radar, and ECM; and fiber optics and broadband telecommunications.

RF Front-End ICs

Analog Devices offers RF Front-End ICs for phased array antenna solutions. These RF Front-End ICs are placed right at the antenna element and can quickly switch between transmit and receive functions in radar applications. The power amplifier on the transmit side is highly efficient operating in short pulse durations. The low noise amplifier on the receive side has a low noise figure with high linearity so that it won’t distort the incoming return signal. The RF Front-End IC also incorporates a high performance switch to toggle between the transmit and receive paths. Highly integrated planar phased array antennae need small form factor solutions, and Analog Devices has integrated the switch, low noise amplifier, and power amplifier into a small surface mount package as well as the decoupling capacitors, providing an optimal solution.

SPDT T/R

Analog Devices provides a range of low cost split path, double throw (SPDT) switches for use in transmit-receive applications that require very low distortion at high incident power levels. Our devices can control from dc to 4 GHz and they are well suited to cellular infrastructure. Applications: • Cellular infrastructure • Private mobile radio handsets • WLAN, WiMAX, and WiBro • Automotive telematics • Test equipment

SPST, SPDT, SP3T, SP4T, SP5T, SP6T, SP8T

Analog Devices' portfolio offers single pole multi-throw (SPDT, SP3T, SP4T, SP6T, SP8T) and single pole single throw (SPST) switches that are ideal for a broad range of applications in military, aerospace, communications, automotive and instrumentation markets. Switches are designed and manufactured in advanced GaAs and Silicon (SOI) processes making them preferable for performance and reliability. The parts exhibit electrical characteristics which is optimized for insertion loss and power handling. SPST, SPDT, SP3T SP4T, SP6T and SP8T versions (reflective and absorptive) offer wide coverage in frequency range and power levels. The switch products are available in both die and packaged form.

Analog Design Tool: ADIsimRF™

ADIsimRF is an easy-to-use RF signal chain calculator. It calculates Cascaded Gain, Noise Figure, IP3, P1dB and Power Consumption. The number of stages can be varied up to a maximum of 20. Stages can be easily inserted, removed or temporarily muted.
