SGA-8343X Reliability Qualification Report

I. Qualification Overview

The SGA-8343X family of products has demonstrated reliable operation by passing all

qualification testing in our product qualification test plan. The “X’ designates a lead-free

lead frame using Tin plated leads. The SGA-8343X has been subject to stresses such as

humidity (autoclave), extreme hot and cold environments (temperature cycling), moisture

sensitivity (MSL-1 and solder reflow testing), and has demonstrated reliable

performance.

II. Introduction

Sirenza Microdevices’ SGA-8343X is a high performance Silicon Germanium

Heterostructure Bipolar Transistor (SiGe HBT) designed for operation from DC to 6 GHz.

The SGA-8343X is optimized for 3V operation but can be biased at 2V for low voltage

battery operated systems. The device provides high gain, low NF, and excellent linearity

at a low cost. It can be operated at very low bias currents in applications where high

linearity is not required.

III. Fabrication Technology

These amplifiers are manufactured using a Silicon Germanium Heterojunction Bipolar

Transistor (HBT) technology. This 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 SGA-8343X power amplifier is packaged in a plastic encapsulated SOT-343

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. The SOT-343 is a similar package differing only by having two fewer leads than

the SOT-363.
