描述 Description

Please note: SKY67103-396LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY67153-396LF

The SKY67103-396LF low-noise amplifier (LNA) with an activebias offers excellent return loss, low noise, and high linearityperformance.

The internal active bias circuitry provides stable performance overtemperature and process variation. The device offers the ability toexternally adjust supply current and gain. Supply voltage isapplied to the RFOUT/VDD pin through an RF choke inductor.Pin 4 (VIN) should be connected to RFOUT/VDD through anexternal resistor to control the supply current. The RFIN andRFOUT/VDD pins should be DC blocked to ensure properoperation. Pin 5 (FEEDBACK) is connected through an RC networkto externally adjust the gain of the device without affecting thenoise figure (NF) of the LNA.

The SKY67103-396LF operates in the frequency range of 0.5 to4.0 GHz with appropriate tuning. The SKY67103-396LF is animproved higher frequency version of the SKY67102-396LF. TheSKY67103-396LF is pin-compatable with the SKY67100-396LFand SKY67101-396LF series of low-noise devices.

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