Description
Integrated enable circuitry
The SKY67023-396LF is GaAs, pHEMT low-noise amplifier (LNA)
with an active bias and high-linearity performance. The advanced
GaAs pHEMT enhancement mode process provides good return
loss, low noise, and high-linearity performance.
Temperature and process-stable active bias
Miniature DFN (8-pin, 2 x 2 mm) package
(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
externally adjust supply current and gain. Supply voltage is
applied to the RFOUT/VDD pin through an RF choke inductor.
Pin 3 (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.
Skyworks GreenTM products are compliant with
all applicable legislation and are halogen-free.

Definition of GreenTM, document number
SQ04–0074.
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
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.
