Filed:

Jan 15, 2007

Appl. No.:

11/623307

Inventors:

Frank M. Caimi - Vero Beach FL, US
Ping Chen - Greensboro NC, US
Young-Min Jo - Viera FL, US

Assignee:

Sky Cross, Inc. - Melbourne FL

International Classification:

H04M 1/00
H04B 1/04
H04Q 11/12

US Classification:

4555501, 455103, 4551273

Abstract:

A communications apparatus comprising a first antenna, a first serial configuration of a first power amplifier and a first matching network, a second serial configuration of a second power amplifier and a second matching network, a switching element for switchably selecting the first or the second serial configuration for supplying a signal to the first antenna, the first and the second power amplifiers supplying a respective first signal of a first power and a second signal of a second power different than the first power to the first antenna for transmitting and the first and the second matching networks presenting respective first and second impedances to the respective first and second power amplifiers, the first and the second impedances responsive respectively to a power-related parameter of the first and the second signals.

US Patent:

20120019420, Jan 26, 2012

Filed:

Aug 15, 2011

Appl. No.:

13/209707

Inventors:

Frank M. Caimi - Vero Beach FL, US
Ping Chen - Greensboro NC, US
Young-Min Jo - Viera FL, US

International Classification:

H01Q 1/50
H01P 11/00
H01Q 1/24

US Classification:

343702, 29600

Abstract:

A modular communications apparatus. The apparatus comprises a dielectric substrate, a radiating structure disposed on a surface of the substrate, and an electronics module disposed within the dielectric substrate. The electronics module comprises a power amplifier and signal receiving components. The apparatus further comprises fixed length transmission lines connecting the radiating structure and the electronics module, a length of each transmission line selected to present a desired impedance at an input and an output terminal of each transmission line without requiring separate impedance matching elements.

International Classification:

H01Q 1/50

US Classification:

343858

Abstract:

A communications apparatus. The apparatus comprises a transmitting antenna, a receiving antenna, a first serial configuration of a first power amplifier and a first matching network for producing a first signal, the first power amplifier operating in a first frequency band, a second serial configuration of a second power amplifier and a second matching network for producing a second signal, the second power amplifier operating in a second frequency band, a first switching element for switchably supplying the first signal or the second signal to the transmitting antenna, a first and a second receiver; and a second switching element for switchably directing a signal received at the receiving antenna to the first receiver or the second receiver.
