Temperature compensated power detector

A temperature compensated power detector, comprising:

• detector means for receiving a power input and producing a voltage output, the voltage output being a positive representation of said power input, said detector means including constant current source means for providing a DC bias, said detector means further including first means for carrying current in one direction wherein said first means is altered by temperature variations;
• and temperature compensation means for canceling out the alteration in said first means, said temperature compensation means operably coupled to said detector means, said temperature compensation means including second means being alterable by temperature variations, and wherein said first means and said second means are in DC series with each other.

A temperature compensated power detector having a selected circuitry, comprising:

• a detector portion including a detector diode, wherein said detector portion receives a power input;
• and a temperature compensation portion operably coupled to said detector portion, said temperature compensation portion including a temperature compensation diode, wherein said detector diode and said temperature compensation diode are in DC series with each other and develop substantially identical voltage drops absent any resistive biasing, wherein the substantially identical voltage drops enable said temperature compensation portion to cancel the affect of a change in voltage to said detector diode and to said temperature compensation diode that is caused by a temperature variation, and wherein the cancellation of the affect enables said power detector to produce a temperature-unaffected output that is representative of said power input.

A temperature compensated power detector for use in a detector circuit operating free of resistive diode biasing, comprising:

• detector means for receiving a power input and producing a voltage output, the voltage output being a positive representative of said power input, said detector means including constant current source means for providing a DC bias current, said detector means further including first means for carrying current in one direction wherein said first means is altered by temperature variations;
• and temperature compensation means for canceling out the alteration in said first means, said temperature compensation means operably coupled to said detector means, said temperature compensation means including second means for carrying current in one direction wherein said second means is altered by temperature variations, and wherein said first means and said second means are in DC series with each other.
