DATA SHEET SKY65386-11: 2575 to 2735 MHz Variable Gain Amplifier Applications Base stations/transmit chains VCTRL Repeater transmit chains Femto cells PA1 Input Match Output Match RF IN PA2 RF OUT Features Variable Attenuator Frequency range: 2575 to 2735 MHz 201729-001 High gain: 25.5 dB Figure 1. SKY65386-11 Block Diagram Attenuation range: 38 dB OP1dB: +28.5 dBm Description OIP3: +44 dBm The SKY65386-11 is a high linearity, variable gain amplifier (VGA). ACLR < -70 dBc (typical) for POUT = +12 dBm The device includes an input linear amplifier, a variable voltage attenuator (VVA), and an output power amplifier (PA). The two Single DC supply: +5 V amplifiers and voltage attenuator are optimized for superior ACLR Small MCM (12-pin, 8.385 x 8.385 mm) SMT package performance with WCDMA signals. (MSL3, 260 C per JEDEC J-STD-020) The high linearity (high OP1dB, OIP3, and ACLR) and high efficiency of this device make it ideal for use at the final stage (or TM close to the final stage) of a wireless transmit chain. Skyworks Green products are compliant with all applicable legislation and are halogen-free. The output of the first PA (PA1) is matched to the input of the VCA. For additional information, refer to Skyworks The output of the VCA is matched to the input of the second PA TM Denition of Green , document number (PA2). The RF IN and RF OUT signals (pins 1 and 8, respectively) SQ040074. are both internally matched, including DC blocking capacitors. The SKY65386-11 VGA uses low-cost surface mount technology (SMT) in the form of a compact, 8.385 x 8.385 mm 12-pin Multi- Chip Module (MCM), which allows for a highly manufacturable low-cost solution. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2.

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. ESD HANDLING: 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 when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. Skyworks Solutions, Inc.
