SKY13270-92LF Block Diagram Low current consumption: <100 A 3 V Ultra-miniature, SC-70 (6-pin, 2.00 x 1.25 mm) package Description (MSL1, 260 C per JEDEC J-STD-020) The SKY13270-92LF is a pHEMT GaAs FET Single Pole Double Throw (SPDT) high linearity switch. This wideband switch is designed for use in systems operating from 20 MHz to 2.7 GHz for which extremely high linearity, low control voltage, high isolation, low insertion loss, and ultra-miniature package size are required. The device is controlled with positive, negative, or a combination of both voltages. The RF signal paths within the device are fully bilateral. The SKY13270-92LF is manufactured in a compact, low-cost 2.00 x 1.25 mm, 6-pin SC-70 package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Figure 2. SKY13270-92LF Pinout 6-Pin SC-70 (Top View) Skyworks Solutions, Inc.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. Technical Description Electrical and Mechanical Specifications The SKY13270-92LF is controlled using two voltage inputs, V1 The absolute maximum ratings of the SKY13270-92LF are and V2 (pins 6 and 4, respectively). Depending on the voltage level provided in Table 2. Electrical specifications are provided in applied to these pins, the common RF port (J1) is connected to Table 3 and the operating characteristics are specified in Table 4. one of two RF ports (J2 or J3) using a low insertion loss path, Typical performance characteristics of the SKYA13270-92LF are while the path between J1 and the other RF port is in its isolation illustrated in Figures 3 through 6. state.
