Abstract
Abstract Structure for controlling the output power from a microwave transmitter uses a digital value transmitted under control of software to an outdoor unit of a transmitter thereby to allow the power output of the transmitter to be changed under control of the software. The digital value is generated by an indoor unit of the transmitter or a remote transmitter across a link or elsewhere in a network. Other parameters of the transmitter can also be varied under control of the software. These parameters include the frequency and muting as well as the generation of test signals at the transmitter. In one embodiment, the outdoor unit contains a non-volatile memory in which the digital value is stored and a microprocessor which generates a control signal from the digital value to set the output power of the transmitter. Software executed by the microprocessor can correct the control signal for temperature so that the output power of the transmitter does not change when outdoor temperature changes.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
A microwave radio system comprising: an indoor unit; an outdoor unit; and a cable connecting the indoor unit to the outdoor unit, wherein: the indoor unit is capable of transmitting to the outdoor unit a first digital value representing a power level to be used by the outdoor unit in transmitting a signal; and the outdoor unit comprises: a nonvolatile memory suitable for receiving and storing the first digital value; a digital-to-analog converter; circuitry for addressing the nonvolatile memory and for providing a second digital value which depends on the first digital value, to the digital-to-analog converter, the digital-to-analog converter converting the second digital value to an analog control voltage; an amplifier which controls an output power of a signal transmitted from the outdoor unit; and structure for applying the analog control voltage to the amplifier thereby to control the output power as a function of the first digital value.
Claim 2
Dependent Claim
150 words
A microwave radio system comprising: an indoor unit; an outdoor unit; and a cable connecting the indoor unit to the outdoor unit, wherein: the indoor unit is capable of transmitting to the outdoor unit a first digital value representing a power level to be used by the outdoor unit in transmitting a signal; and the outdoor unit comprises: a nonvolatile memory suitable for receiving and storing the first digital value; a digital-to-analog converter; circuitry for addressing the nonvolatile memory and for providing a second digital value which depends on the first digital value, to the digital-to-analog converter, the digital-to-analog converter converting the second digital value to an analog control voltage; an amplifier which controls an output power of a signal transmitted from the outdoor unit; and structure for applying the analog control voltage to the amplifier thereby to control the output power as a function of the first digital value.
Claim 3
Dependent Claim

Claim 9
Independent Claim
104 words
A method for controlling operation of an RF assembly of a microwave transmitter, comprising: transmitting a telemetry signal from a remote radio to the RF assembly through a microwave link; transmitting the telemetry signal from the RF assembly to an indoor unit; extracting from the telemetry signal a command to change an operating parameter of the RF assembly, wherein in response the command, the indoor unit transmits a digital value from the indoor unit to the RF assembly; storing the digital value in a nonvolatile memory located in the RF assembly; and using the digital value as an operating parameter for the RF assembly.
Claim 10
Independent Claim
104 words
A method for controlling operation of an RF assembly of a microwave transmitter, comprising: transmitting a telemetry signal from a remote radio to the RF assembly through a microwave link; transmitting the telemetry signal from the RF assembly to an indoor unit; extracting from the telemetry signal a command to change an operating parameter of the RF assembly, wherein in response the command, the indoor unit transmits a digital value from the indoor unit to the RF assembly; storing the digital value in a nonvolatile memory located in the RF assembly; and using the digital value as an operating parameter for the RF assembly.
Claim 11
Dependent Claim
24 words
