SGL-0622Z Reliability Qualification Report
I. Qualification Overview
The SGL-0622Z product has been qualified by similarity to a qualification vehicle that
passed all qualification testing in our product qualification test plan. Stresses such as
operating life, humidity (autoclave), extreme hot and cold environments (temperature
cycling), and moisture sensitivity (MSL-1 and solder reflow testing) were performed with
satisfactory results.
II. Introduction
The SGL-0622Z is a low power, high gain, fully matched LNA designed for 0.1 – 4GHz
operation. This LNA is designed for low power, 2.7 to 3.6V battery operation. This
amplifier is fully matched and requires only 4-5 external components to achieve 28.5 dB
gain at 1.575GHz and a noise figure of 1.45dB.
III. Fabrication Technology
These amplifiers are manufactured using a Silicon Germanium Heterojunction Bipolar
Transistor (HBT) technology. This patented self-aligned emitter, double poly HBT
process has been in production by our foundry since 1998. The process has been
successfully used for a wide range of RFIC products including GSM PAs, DECT front
end transceivers, LNAs & VCOs. This process offers comparable performance to GaAs
HBTs with the added advantages of mature and high producible Silicon wafer
processing.
IV. Package Type
The SGL-0622Z is packaged in a plastic encapsulated 2mm X 2mm Quad Flat Pack NoLead (QFN) package that is assembled using a highly reproducible automated assembly
process. The die is mounted using an industry standard thermally and electrically
conductive silver epoxy.

V. Qualification Methodology
The Sirenza Microdevices qualification process consists of a series of tests designed to
stress various potential failure mechanisms. This testing is performed to ensure that
Sirenza Microdevices products are robust against potential failure modes that could arise
from the various die and package failure mechanisms stressed. The qualification testing
is based on JEDEC test methods common to the semiconductor industry. A FMEA
approach is used to determine the test methods to be included in the qualification plan.
VI. Qualification By Similarity
A product can be qualified by similarity using a qualification vehicle provided that no
new potential failure modes/mechanisms are possible in the product. The SGL-0622Z is
qualified using a qualification vehicle that is manufactured with the same technology and
assembly processes.
VII. Operational Life Testing
Sirenza Microdevices defines operational life testing as a DC biased elevated
temperature test performed at the maximum junction temperature limit. For the
qualification vehicle and the SGL-0622Z, the maximum operational junction temperature
limit is 150oC. The purpose of the operational life test is to statistically show that the
product operated at its maximum operational ratings will be reliable by operating devices
up of 1000 hours. The results for this test are expressed in device hours that are
calculated by multiplying the total number of devices passing the test by the number of
hours tested.
VIII. Moisture Sensitivity Level - MSL Level 1 Device
The qualification vehicle successfully completed 168 hours of moisture soak
(85oC/85%RH), followed by three passes through a convection reflow oven at 270oC.
The successful completion of this test classifies the SGL-0622Z as JESD 22-A113B
Moisture Sensitivity Level 1 (MSL-1). MSL-1 indicates that no special dry pack
requirements or time limits from opening of static bag to reflow exist for the SGL-0622Z.
MSL-1 is highest level of moisture resistance that a device can be classified according to
the above mentioned standard.

IX. Electrostatic Discharge Classification
Sirenza Microdevices classifies Human Body Model (HBM) electrostatic discharge (ESD)
according to the JESD22-A114 convention. All pin pair combinations were tested on the
SGL-0622Z. Each pin pair is stressed at one static voltage level using 1 positive and 1
negative pulse polarity to determine the weakest pin pair combination. The weakest pin
pair is tested with 3 devices below and above the failure voltage to classify the part. The
Pass/Fail status of a part is determined by the manufacturing test specification. The
ESD class quoted indicates that the device passed exposure to a certain voltage, but
does not pass the next higher level. The following table indicates the JESD ESD
sensitivity classification levels.

XIII. Junction Temperature Determination
One key issue in performing qualification testing is to accurately determine the junction
temperature of the device. Sirenza Microdevices uses a 3um spot size emissivity
corrected infrared camera measurement to resolve the surface temperature of the device
at the maximum operational power dissipation. The results are displayed below for the
SGL-0622Z device running at operational current of Id=12mA, a device voltage of 3.3V,
lead temperature of 85°C.
Tj=90.7°C
