• Adjustable supply current and gain

• Temperature and process-stable active bias

Description

• Miniature DFN (8-pin, 2 x 2 mm) package (MSL1 @ 260 °C per

JEDEC J-STD-020)

The SKY67110-396LF is GaAs, pHEMT Low-Noise Amplifier (LNA)

with an active bias and high linearity performance. The advanced

GaAs pHEMT enhancement mode process provides excellent

return loss, low noise, and high linearity performance.

The internal active bias circuitry provides stable performance over

temperature and process variation. The device offers 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

(VBIAS) should be connected to RFOUT/VDD through an external

resistor to control the supply current. The RFIN and RFOUT/VDD

pins should be DC blocked to ensure proper operation. 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.

The SKY67110-396LF operates in the frequency range of 0.30 to

0.75 GHz with proper tuning.

The LNA is manufactured in a compact, 2 x 2 mm, 8-pin Dual Flat

No-Lead (DFN) package. A functional block diagram is shown in

Figure 1. The pin configuration and package are shown in

Figure 2. Signal pin assignments and functional pin descriptions

are provided in Table 1.
