PRODUCT DESCRIPTION
SST12LN01 provides high-performance, low-noise,
and moderate-gain operation within the 2.4–2.5 GHz
frequency band. Across this frequency band, the LNA
typically provides 13.5 dB gain and 1.5 dB noise figure.
This LNA cell is designed with a self DC-biasing
scheme, which maintains low DC current consumption,
nominally at 10 mA, during operation. Optimum performance is achieved with only a single power supply, and
no external bias resistors or networks are required. The
input and output ports are single-ended 50 matched.
RF ports are also DC isolated requiring no DC blocking
capacitors or matching components.
SST12LN01 is offered in a 6-contact UQFN package.
See Figure 3-1 for pin assignments and Table 4-1 for
pin descriptions.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
