NGA-689

Preliminary Product Description Sirenza Microdevices’ NGA-689 is a high performance Gallium Arsenide Heterojunction Bipolar Transistor MMIC Amplifier. Designed with InGaP process technology for improved reliability, a Darlington configuration is utilized for broadband performance up to 5 Ghz. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products.

Mounting Instructions 1. Solder the copper pad on the backside of the device package to the ground plane. 2. Use a large ground pad area with many plated through-holes as shown. 3. We recommend 1 or 2 ounce copper. Measurement for this data sheet were made on a 31 mil thick FR-4 board with 1 ounce copper on both sides. LC CD CB CB Part Identification Marking The part will be marked with an “N6” designator on the top surface of the package. 4 Pin # 1 Function RF IN Description RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possible. N6 1 2 3 2 2, 4 GND 3 For package dimensions, refer to outline drawing at www.sirenza.com RF OUT/ RF output and bias pin. DC voltage is BIAS present on this pin, therefore a DC blocking capacitor is necessary for proper operation. 1 3 Caution: ESD sensitive Part Number Ordering Information Part Number NGA-689 Reel Size 7" Devices/Reel 1000 Appropriate precautions in handling, packaging and testing devices must be observed. 522 Almanor Ave., Sunnyvale, CA 94085 Phone: (800) SMI-MMIC 5 http://www.sirenza.com EDS-101442 Rev OBS Preliminary OBSOLETE NGA-689 DC-5.0 GHz 5.8V GaAs HBT PCB Pad Layout Dimensions in inches [millimeters] Dimensions in inches [millimeters] Refer to package drawing posted at www.sirenza.com for tolerances.
