Two-way Power Divider

This two-way power divider operates in a frequency range from 350 to 6000 MHz. The broad frequency coverage allows multiple bands to share a common antenna or distributed antenna system. The design uses a multi-section microstrip design to achieve the bandwidth, offer adequate isolation and good input and output VSWR at a moderate price.

Integrated Circuit

GaAs Integrated Circuits

The first three members of this multi-function circuit (MFC) family of high performance GaAs ICs for point-to-point radio and satellite communications are the TG4402, TGC4403 and TGC4405. They address OEM needs for frequency upconversion in the transmit and local oscillator chains. The TGC4405 provides a high level of integration for designs that specify RF upconversion, a local oscillator frequency doubler and output RF signal amplification in a small, single product. The TGC4402 was created for designs that require upconversion without an integral LO doubler or output amplifier, while the TGC4403 is a millimeter-wave frequency doubler that includes an output buffer amplifier. Both the TGC4405 and TG4402 employ single-ended designs and therefore do not require external baluns.
