ta Ft PASTERNACK M* THE ENGINEER'S RF SOURCE 60GHz Baseboard I/Q Module Description The PEM004 is a 500 MHz quadrature signal source for use with the PEM003-KIT 60 GHz waveguide development system transmitter. The transmitter provides for baseband signal inputs in the form of Inphase (I) and Quadrature-phase (Q) waveforms, also called vector waveforms. The vector waveforms are often created by digital to analog (D/A) converters that are part of a digital modulation system for wireless communications. However, there may be situations where that kind of modulation system has yet to be developed, or a simple continuous wave (CW) carrier is desired from the 60 GHz transmitter for testing purposes. Any vector modulated transmitter can produce a simple CW carrier if a sine wave is fed into the I and Q baseband inputs with a phase delay of 90° between them. If the Q input signal is delayed relative to the I input signal by 90°, the 60 GHz output will be as an upper sideband CW signal with the carrier frequency and the lower sideband signal suppressed. Mathematically, the I-input signal is the cosine, and the Qinput signal is the sine, at a frequency of 500 MHz. The 60 GHz frequency of the upper sideband signal will simply be the baseband signal frequency added to the carrier frequency. In the case of the PEM004, the frequency is set at 500 MHz. Therefore the resulting upper sideband frequency at 60 GHz will be the 60 GHz transmitter carrier frequency setting plus 500 MHz. As an example, if the PEM003-KIT transmitter carrier is set at 58.32 GHz, and the PEM004 is connected to the I and Q baseband inputs, the resulting frequency at the transmitter output will be 58.32 GHz + 500 MHz = 58.82 GHz. The original carrier frequency at 58.32 GHz will be suppressed, as well as the lower sideband frequency at 58.32 - 500 MHz = 57.82 GHz. The PEM004 provides a stable, clean 500 MHz waveform with tightly controlled phase between the I and Q outputs. The PEM004 comes with all cables necessary for connecting to the PEM003-KIT transmitter board. The power cable plugs directly into J1 on the front of transmitter board (lower right) which provides 3.3VDC to the PEM004. The I and Q baseband signals are connected via their marked coaxial cables to the coaxial expansion board on the rear side of the transmitter assembly.
