IDT opens new product line with 8 GHz RF switch

October 24, 2014 // By Graham Prophet
The first in a line of radio frequency switch ICs, and featuring ultra-high isolation and linearity, the F2912 is an absorptive 50Ω SP2T RF switch aimed at base stations (2G, 3G and 4G), microwave backhaul and front haul, test equipment, CATV headend, WiMAX radios, and wireless systems.

The F2912 lists features that include:

- Frequency range of 300 kHz to 8 GHz, achieving broad bandwidth without sacrificing performance across the entire frequency range.

- Low insertion loss of 0.4 dB, providing low path loss without compromising isolation performance.

- High isolation of 60 dB at 2 GHz to reduce signal leakage between adjacent RF port paths.

- High OIP3 of +64 dBm to reduce intermodulation distortion.

- P1dB of 30 dBm, providing 1W compression point, ensuring rugged operation for a variety of applications.

- 3.3 V and 1.8 V control logic consistent with common FPGA and microcontroller logic levels – no negative supply/control voltage is required. DC current from a 3.3V line is 20 µA.

- Operating temperature range of -55 to 125°C for high reliability in harsh thermal environments.

- Switching time of around 1 µsec.

“The F2912 represents IDT's entry into the RF switch market, where it integrates seamlessly with our other leading RF products to provide engineers a reliable and efficient development path,” said Chris Stephens, IDT’s senior director of Wireless Product Definition and Marketing.
