A multi-band radio having seamless satellite communication capability is provided. The radio includes: a user interface for controlling operations of the radio; an encryption module; a LOS wireless transceiver for transmitting encrypted data at a frequency in the radio frequency spectrum; a BLOS wireless transceiver for transmitting encrypted data at a frequency in the microwave frequency spectrum; and a router for routing the encrypted data to at least one of the LOS transceiver and the BLOS transceiver.

A bi-directional amplifier having two symmetrical and versatile impedance matching circuits with a JFET therebetween, and a method for bi-directional amplification using a JFET. Each junction of the JFET may be a drain or a source depending on the direction of amplification. Each impedance matching circuit provides a low impedance for the junction that is a source and a high impedance for the junction that is a drain. The impedance is varied by adding a first capacitor parallel to a resonating inductor and a second capacitor, which is removed or inserted in series with the load, responsive to the direction of amplification. The frequency of the signal being amplified may be different for each direction.

A cellular mobile telephone system and method in which channel assignment and telephone call routing are controlled by a central control station and in which each communications channel is separately controlled at a cell station by a radio interface module ('RIM') associated therewith. Flexibility and security from operational interruptions is provided by dynamic assignment of identical RIMs to monitoring, paging, control and communication functions at the cell station. The system is modular and may be customized to accommodate geographic and demographic considerations, while permitting expansion and modification without obsolescence. The system also includes novel, self-diagnostic testing loops and methods. A novel mobile telephone is also disclosed.
