Product Description The SGA-689 is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration featuring micron emitters provides high F T and excellent thermal perfomance. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products. Only DC-blocking capacitors, a bias resistor and an optional RF choke are required for operation. The matte tin finish on Sirenza s lead-free package utilizes a post annealing process to mitigate tin whisker formation and is RoHS compliant per EU Directive /95. This package is also manufactured with green molding compounds that contain no antimony trioxide nor halogenated fire retardants.

Solder the copper pad on the backside of the device package to the ground plane.. Use a large ground pad area with many plated through-holes as shown.. We recommend or ounce copper. Measurement for this data sheet were made on a mil thick FR- board with ounce copper on both sides. Part Identification Marking A6 A6Z Pin # Function RF IN, GND RF OUT/ BIAS Description RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. Connection to ground. For optimum RF performance, use via holes as close to ground leads as possible to reduce lead inductance. RF output and bias pin. DC voltage is present on this pin, therefore a DC blocking capacitor is necessary for proper operation. Caution: ESD sensitive Appropriate precautions in handling, packaging and testing devices must be observed.
