High Frequency SMA End Launch Connectors Applications High Frequency SMA End Launch Connectors for Microwave PC Board Substrates The Johnson Patent Pending High Frequency End Launch connectors are used to transition microwave energy from coaxial to planar transmission line structures. These patent pending connectors provide a unique solution for microwave engineers who fabricate circuit designs on very thin high frequency board substrates. The in-line connector design minimizes reections as compared to a right-angle (perpendicular) pc mount transition. Applications for these connectors include: Cellular Linear Power Ampliers Broadband MMIC Power Ampliers Microwave Filters, Mixers and Combiners Wireless Infrastructure Antennas DBS Low-Noise Block Down Converters Remote Sensing and Metering Global Positioning Satellite Antennas Phased Array Antennas Radar Systems High Speed Routers and Switches Automated Test Equipment Typical Return Loss RF Identication Tags Measured on 50 ohm GCPW fabricated on Rogers RO-4003 substrate 142-0761-811 (8 mil substrate) 142-0761-871 (16 mil substrate) VSWR = 1.05+.02F(GHz) The Johnson High Frequency End -10 Launch connector is designed to attach directly to a high frequency coplanar waveguide (CPW) circuit -20 board transmission line, although other lines such as microstrip can be used with good results. These -30 connectors can be used on high frequency PC board substrate layers as thin as 8 mils, and operate at -40 frequencies up to 26.5 GHz (see Return Loss chart). -50 PATENT PENDING 0 10 15 5 20 25 30 Frequency (GHz) 2 Emerson Network Power Tel: 800.247.8256 Fax 507.833.6287 www.EmersonNetworkPower.com/connectivity S11 (dB)
