A Darlington configuration featuring 1 micron emitters provides high FT 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 2 DC-blocking ca- pacitors, 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 whis- ker formation and is RoHS compliant per EU Direc- tive 2002/95. This package is also manufactured with green molding compounds that contain no an- timony trioxide nor halogenated fire retardants.

OIP 3 Tone Spacing = 1 MHz, Pout per tone = 0 dBm Bias Resistance = 26 Ohms T L = 25ºC Z S = ZL = 50 Ohms NOTE: The recommended operating current in the preliminary datasheet was 130mA. Supplemental measurements have since shown that an operating current of 115mA results in optimal RF performance over temperature. Continued operation at 130mA is reliable, however, the recommended operating current has been changed to 115mA. |
