Abstract

The architecture of mobile transceiver with external coax connector for a car-kit with external antenna are based on an antenna for transmit and receive. This invention comprises a combination of a multiband /wideband transceiver and a car-kid. It allows a handling by an internal wireless device antenna or an external car-kid antenna (Fig. 1). Multiband / wideband transceivers with separated antenna to transmit and receive have one connector in the transmit and the other in the receive path. The connector consists of a front contact cable plug (90°) and a switching SMD-jack (Short Message Delivery, SMD) mounted on PCB (Printed Circuit Board, PCB). By placing the wireless device in the holder the mechanical pressure actuates the external connector switch which changes the signal path from internal wireless device antenna over to an external car-kid connector. As an external multiband / wideband is desired, the transmit and receive path are brought together to an antenna with a circulator which is placed in the holder of the car-kid. The circulator separates and duplexes the transmit and receive signal. For the transmitting it could be employed a frequency-tunable antenna.

The architecture of mobile transceiver with external coax connector for a car-kit with external antenna are based on an antenna for transmit and receive.

This invention comprises a combination of a multiband /wideband transceiver and a car-kid. It allows a handling by an internal wireless device antenna or an external car-kid antenna (Fig. 1). Multiband / wideband transceivers with separated antenna to transmit and receive have one connector in the transmit and the other in the receive path. The connector consists of a front contact cable plug (90°) and a switching SMD-jack (Short Message Delivery, SMD) mounted on PCB (Printed Circuit Board, PCB). By placing the wireless device in the holder the mechanical pressure actuates the external connector switch which changes the signal path from internal wireless device antenna over to an external car-kid connector. As an external multiband / wideband is desired, the transmit and receive path are brought together to an antenna with a circulator which is placed in the holder of the car-kid. The circulator separates and duplexes the transmit and receive signal. For the transmitting it could be employed a frequency-tunable antenna.

This solution allows to decrease the filter rejection and intermodulation requirements...
