Transcription

1 SCG2 Features DC to 6 MHz 2 db Gain at 1 MHz 15 dbm Output P1dB at 1 MHz 29 dbm Output IP3 at 1 MHz 3.8 db Noise Figure at 2 MHz Applications Broadband Gain Blocks High Linearity Amplifiers Packages Available (-B) SOT-89 (-BL) SOT-89 (Lead Free) Description The SCG2B is a high reliability, high linearity, low cost broadband amplifier, optimized for commercial communications. The device is manufactured using in-house developed, advanced Indium Gallium Phosphide Heterojunction Bipolar Transistor (InGaP HBT) technology and is designed for use as a 5 Ohm gain block. The amplifier features excellent VSWR, low noise figure and highly linear performance. Typical OIP3 is +29dBm at 1MHz. The SCG2B operates from a single voltage supply and requires only two DC-blocking capacitors, a bias resistor and an inductor for operation. The device is ideal for wireless applications and is available in a low cost, surface-mountable SOT-89 packages. The SCG2B is designed in the Darlington configuration with direct feed back. Its operation frequency at low end is limited only by the dc blocking capacitor and the RF choke inductor (large values are required in both cases).

It requires a DC blocking capacitor large 1 RFin enough to handle the lowest frequency used. The two ground connections should be directly connected together to the ground plane on 2, 4 Gnd the PCB. The ground connection also serves as a heatsink. 3 RFout This pin has a nominal 5 ohm output impedance. It requires a DC bias of 45mA through a series inductor and a resistor. A bypass capacitor (1. micro Farad) on the DC side of the inductor is recommended for providing instantaneous current during a modulated RF signal. Use a DC blocking capacitor on the output with similar requirements as the input side. EiC Corp. A Subsidiary of EiC Enterprises, Ltd Northport Loop West, Fremont, CA Phone: (51) Fax: (51)

3 SCG2 Thermal Specifications Thermal resistance, Rth SOT 89 pkg. 12 C/W Tj 23 C The thermal resistance is referenced from the junction to bottom of the ground of the package. Reliability and Burn-In Test EiC performs burn-in for selected lots on a regular basis to monitor and guarantee consistent product quality and reliability. The burn-in process consists of pre-conditioning (JESD22-A113-B), pre and post RF tests, and bias life (JESD22- A18-A). The table is based on the following parameters and conditions: Activation Energy: 1.85eV Junction to Ambient Temperature Difference: +23 o C Confidence levels of 6% and 9% are used to calculate FIT (Failure In Time), for the nominal operating ambient temperature at +25 o C. Test Temp Hours Completed Quantity Tested Quantity Failed +145 C C 1 2 Cumulative 6% Confidence Level (Tj=65 C) Cumulative 6% Confidence Level (FIT <1) Cumulative 9% Confidence Level (Tj=65 C) Cumulative 9% Confidence Level (FIT <1) < E+11 Hours < E+1 Hours EiC will update the burn-in and cumulative FIT results periodically.
