Description:
The uPG2150T5L-EVAL-A evaluation board provides a quick and convenient means of
evaluating the performance of the NEC uPG2150T5L switch. In addition to the device, the board
provides DC block capacitors, power supply bypass capacitors, and RF and DC connectors.
A DC block capacitor is required at all RF ports. On this board, two parallel capacitors of 22pF are
used for this purpose. This configuration minimizes the mismatch effect associated with the serial
capacitors over a wide frequency range. In a real application where the operation frequency
range is relatively narrow, one DC block capacitor usually is sufficient. The user should select the
appropriate capacitor value according to the operation frequencies and the type of capacitor
selected. Generally the performance of the switch circuit is not sensitive, to a certain extent, to
the value of DC block capacitors.
A 1000pF DC bypass capacitor is used on all control lines. For high speed applications the user
may choose smaller capacitance or no capacitor at all.
