SKY67100-396LF数据手册RF/IF射频/中频RFID的射频放大器规格书PDF

描述 Description

Please note: SKY67100-396LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY67154-396LF

The SKY67100-396LF is GaAs, pHEMT Low-Noise Amplifier (LNA)with an active bias and high linearity performance. The advancedGaAs pHEMT enhancement mode process provides excellentreturn loss, low noise, and high linearity performance.

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. Pin4 (VIN) should be connected to RFOUT/VDD through an externalresistor to control the supply current. The RFIN and RFOUT/VDDpins should be DC blocked to ensure proper operation. Pin 5(FEEDBACK) is connected through an RC network to externallyadjust the gain of the device without affecting the Noise Figure(NF) of the LNA.

The SKY67100-396LF operates in the frequency range of 1.2 to3.0 GHz. For lower frequency operation, the pin-compatibleSKY67101-396LF should be used.

The switch is manufactured in a compact, 2 x 2 mm, 8-pin DualFlat No-Lead (DFN) package.
