SKY67102-396LF

2.0 – 3.0 GHz High Linearity, Active Bias Low-Noise Amplifier


The SKY67102-396LF is a GaAs, pHEMT Low-Noise Amplifier (LNA) with integrated active bias, high linearity (+34 dBm OIP3) and <1.0 dB Noise Figure at 2.6 GHz. The advanced GaAs pHEMT enhancement mode process also provides good return loss, high gain, unconditional stability and high reverse isolation.

The internal active bias circuitry provides stable performance over temperature and process variation. The device offers the user the ability to externally adjust supply current and gain. Supply voltage is applied to the RFOUT/VDD pin through an RF choke inductor. Pin 4 (VIN) should be connected RFOUT/VDD through an external resistor to control the supply current. Pin 5 (FEEDBACK) is connected through an RC network to externally adjust the gain of the device without affecting the Noise Figure (NF) of the LNA. In addition, the RFIN and RFOUT/VDD pins should be DC blocked to ensure proper operation.

The SKY67102-396LF is optimized for the frequency range of 2.3 to 3.0 GHz. For 0.4 to 1.2 GHz operation, the SKY67101-396LF should be used and for 1.2 to 2.2 GHz operation the pin-compatible SKY67100-396LF is recommended.

The LNA is manufactured in a compact, 2 x 2 mm, 8-pin Dual Flat No-Lead (DFN) Skyworks Green package.
