SKY67023-396LF Block Diagram Gain: 17.3 dB 2.6 GHz Adjustable supply current Description Integrated enable circuitry The SKY67023-396LF is GaAs, pHEMT low-noise amplifier (LNA) Temperature and process-stable active bias with an active bias and high-linearity performance. The advanced GaAs pHEMT enhancement mode process provides good return Miniature DFN (8-pin, 2 x 2 mm) package loss, low noise, and high-linearity performance. (MSL1 260 C per JEDEC J-STD-020) The internal active bias circuitry provides stable performance over temperature and process variation. The device offers the ability to TM Skyworks Green products are compliant with externally adjust supply current and gain. Supply voltage is all applicable legislation and are halogen-free. applied to the RFOUT/VDD pin through an RF choke inductor. For additional information, refer to Skyworks Pin 3 (VBIAS) should be connected to RFOUT/VDD through an TM Denition of Green , document number external resistor to control the supply current. The RFIN and SQ040074. RFOUT/VDD pins should be DC blocked to ensure proper operation. The SKY67023-396LF operates in the frequency range of 2.2 to 3.0 GHz. For lower frequency operation, the pin-compatible SKY67022-396LF or SKY67021-396LF should be used. The LNA is manufactured in a compact, 2 x 2 mm, 8-pin Dual Flat 1 8 N/C N/C No-Lead (DFN) package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in 2 7 RFIN RFOUT/VDD 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. Exceeding any of the limits listed here may result in permanent damage to the device. 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.
