National Instruments 780277-01 I/Q Modulator Module

Part Number 780277-01 is the identifying part number for the National Instruments PXIe-5611 I/Q Modulator Module. The 780277-01 is a part of the PXIe-5673E Vector Signal Generator Module. The vector signal also consists of other modules in addition to the I/Q modulator, namely the PXIe-5450/5451 Waveform Generator and the PXIe-5650/5651/5652 RF Analog Signal Generator (LO source). Note that PXIe-5673E is not a physical device but a group of independent modules. Moreover, there is also a similar device with a different part number: 780277-11 representing the 6.6 GHZ IQ Enhanced Modulator.

The 780277-01 supports a frequency of 6.6 GHz. The nominal input power is 0 dBm while the input impedance is 50 Ω. Similarly, the input VSWR is <2:1. Furthermore, the absolute maximum power is +18 dBm while the maximum DC power is ±5 VDC. On the other hand, the output power is typically 0 dBm, ±1.0 dB and the output power resolution is 0.5 dB. The nominal output impedance is 50 Ω while the output VSWR is dependent on the frequency range. The 780277-01 measures (8.5 in. × 0.8 in. × 5.1 in.) in physical dimensions and weighs 20 oz. The module utilizes 0.6 A of current at a supply of +3.3 VDC while at +12 VDC, the typical current is 0.7 A while the maximum current can be 0.8 A. The power consumption is typically 10.5 W. Furthermore, the module supports the SMA female-type connector. 

The 780277-01 is recommended for operation at an ambient temperature range of 0 °C to 55 °C and a relative humidity range of 10% to 90% (noncondensing). Likewise, the module should only be used in indoor spaces and up to a maximum altitude of 2000m (corresponding to an atmospheric pressure of 800 mbar at 25 °C ambient temperature). Furthermore, the module can be stored at a temperature range of -40 °C to 71 °C at a relative humidity of 5% to 95% (noncondensing). The recommended calibration interval for the module is 1 year.
