The device provides high linearity, low insertion loss, and high isolation. Switching is controlled by four control voltage inputs (CTRL1, CTRL2, CTRL3, and CTRL4). Depending on the logic voltage level applied to the control pins, the four RF ports (RF1, RF2, RF3, and RF4) are connected together using a low insertion loss path, while maintaining a high isolation path to the alternate N/C RF1 N/C ports. Series DC blocking capacitors are required on all RF ports for proper operation. 12 11 10 The SKY13353-337LF is provided in a 3 x 3 mm, 12-pin Quad Flat No-Lead (QFN) package. A functional block diagram is shown in CTRL1 1 9 CTRL2 Figure 1. The pin configuration and package are shown in RF3 2 8 RF4 Figure 2.
