Shipping to the US is $6. $15 for the rest of the world. I will combine auctions to lower shipping costs.   Pin # Signal Name Range Nominal Function 1 +5 VDC IP_5VDC 5.0­+0.25V +5.0V +5 V 2 -5.25 VDC IP_NEG5P25VDC -5.25 +0.25V -5.25V -5.25 V 3 Temperature Sensor PI_PDET_TEMP 0 to 2V N/A Temperature Sensor Output 4 Power Detector  (-), Low Power Range PI_PDET_NEG_LOW -2.5 to +2.5 V N/A Detector Negative Output, Low Power range 5 Power Detector  (+), Low Power Range PI_PDET_POS_LOW -2.5 to +2.5 V N/A Detector Positive Output, Low Power range 6 Power Detector  (-), High Power Range PI_PDET_NEG_HI -2.5 to +2.5 V N/A Detector Negative Output, High Power range 7 Power Detector  (+), High Power Range PI_PDET_POS_HI -2.5 to +2.5 V N/A Detector Positive Output, High Power range 8 Detector Bias Control IP_DETBIAS_CNTL 0 to 3.3 V 0 to 3.3 V Detector bias control, “1” = High Power range 9 Ground GND N/A 0 V Ground Power Detector Module is part of the TX power control circuitry in the ODU assembly. During TX power setting, the 2-tone TX power (P2T) is first calculated by adding the TR spacing offset (dPTRx), modulation offset (dPxQ) and ODU power offset (dPTXOS) to the desired TX power (PTX). The address of the power detector data can then be determined with the 2-tone TX power, TX frequency and the operating temperature from temperature sensor. The detector data will be used in the ALC loop as a feedback signal to set the TX output. To improve the power accuracy, the ODU power offset dPTXOS shall be calculated by interpolation over TX frequency, and the power detector data shall also be interpolated over TX power and frequency
