PRECAUTIONS

[1] The DC blocking capacitors have to be placed at RF terminal of P1, P2 and PC.

[2] Bypass capacitors (C4, C5) should be placed close to terminals of VCTL1, VCTL2 to reduce

stripline influence of RF characteristics.

[3] For good isolation, the GND terminal (2nd pin) must be placed possibly close to ground

plane of substrate, and through holes for GND should be placed near by the pin connection.

[4] To avoid degradation of isolation or high power characteristics, please layout ground

pattern right under this IC.
