Enhanced Time Division Duplexing (Tdd) Transceiver Circuitry
US Patent:
6591086, Jul 8, 2003
Filed:
Apr 24, 2000
Appl. No.:
09/557242
Inventors:
Wayne E. Pleasant - Turners Falls MA
Assignee:
Telaxis Communications Corporation - South Deerfield MA
International Classification:
H04B 144
US Classification:
455 78, 455 24, 455 673, 370278, 370280, 370282
Abstract:
A communication transceiver circuit intended for operation in a Time Division Duplex (TDD) system. The configuration eliminates the need for transmit-receive switches and the circuitry needed to operate them. Instead, a three port circulator is used to couple a transmitter section and receiver section to a common antenna. A signal power detector and blanking circuit are coupled to the receiver section input and arranged to generate a blanking signal for an input receiver amplifier. This disables the receiver during conditions when power reflected back through the antenna and circulator would otherwise saturate the receiver. In a preferred environment, a second circulator is connected to an intermediate frequency (IF) side of the transceiver together with a pair of isolators to permit the transceiver to be connected to IF equipment with a single cable.
High-Speed Point-To-Point Modem-Less Microwave Radio Frequency Link Using Direct Frequency Modulation
US Patent:
6823178, Nov 23, 2004
Filed:
Feb 14, 2001
Appl. No.:
09/783722

Assignee:
YDI Wireless, Inc. - South Deerfield MA
International Classification:
H04B 7155
US Classification:
455119, 455 21
Abstract:
A point-to-point microwave radio link that operates in a Frequency Division Duplex (FDD) mode using direct digital modulation with a Continuous Phase-Frequency Shift Keyed (CP-FSK) scheme. The transmit signal is generated by a circuit that uses a Voltage-Control Oscillator (VCO) operating in a microwave radio band. The VCO is deviated over a narrow frequency range that is reduced by a predetermined factor. The output of the VCO is then frequency multiplied by the predetermined factor to produce the modulated microwave output signal at the desired band. The deviation frequency of the VCO is thus chosen to be the reciprocal of the multiplication factor times the transport bit rate.

International Classification:
H04B003/04
US Classification:
333/017100
Abstract:
A point-to-point microwave radio link that operates in a Frequency Division Duplex (FDD) mode using direct digital modulation with a Continuous Phase Shift Keyed (PSK) scheme. The transmit signal is generated by a circuit that uses a Voltage-Control Oscillator (VCO) operating in a microwave radio band to obtain the modulated signal. The VCO output is fed to a phase modulator to obtain the modulated signal. The output of the VCO is then frequency multiplied by the predetermined factor to produce the modulated microwave output signal at the desired band.

US Classification:
725/073000, 455/003010, 455/003050
Abstract:
A point-to-point microwave radio link that operates in a Frequency Division Duplex (FDD) mode using direct digital modulation with an ON-OFF Keyed (OOK) scheme. The transmit signal is generated by a circuit that uses an oscillator operating in a microwave radio band. The oscillator output is switched at the input bit rate. The output of the switched oscillator is then frequency multiplied by the predetermined factor to produce the modulated microwave output signal at the desired band.
Wireless Data Communication Device
US Patent:
2006003, Feb 16, 2006
Filed:
Aug 12, 2005
Appl. No.:
11/202746
Inventors:
Wayne Pleasant - Turners Falls MA, US
International Classification:
H04B 1/26, H04M 1/00
US Classification:
455313000, 455550100
Abstract:
A radio communication device is disclosed. A millimeter range mixer having a first immediate frequency port, a second reference port, and a millimeter wave port receives an intermediate frequency radio signal. A local oscillator source provides a reference signal to the reference port of the mixer, and using a millimeter wave filter coupled to the millimeter wave port of the mixer, the intermediate frequency radio signal is converted to a millimeter wave frequency signal.
