2 With built-in plug-and-play functionality, Molex s Mobile TV Standard Antenna integrates LDS technology to eliminate the need for external attachments or active CMMB control chips Molex s Passive, Internal Mobile TV Standard Antenna (Series 47951)

3 Key Strengths of Mobile TV Antenna The first of its kind offered by Molex internal, passive Developed specially for the China Multimedia Mobile Broadcasting (CMMB) format Plug-and-Play integration without the need for: external whip antennas costly active circuitry, switches, tuning components or any complex interface to the mobile device receiver for active frequency tuning engineering resources to integrate tunable antenna with the CMMB receiver Integral snap-in hooks mounts antenna precisely and securely to mobile device cover Antenna is RoHS-compliant and halogen-free

4 Product Features LDS-grade carrier (antenna housing) Nickel (Ni) over Copper (Cu) circuit traces Contact area (pin 1 and 2) connects to source and ground inductors of the matching network Antenna with integral location pin recesses and snap-in hooks (Fig. 1) Location-pin recess Nickel-over- Copper plated traces (pin 2) Location-pin recess Hook Antenna carrier Hook Nickel-over- Copper plated traces (pin 1) Figure 1. Design features of a Mobile TV Standard Antenna

5 Product Features (continued) Locating pins on the cover fit the recesses neatly Easy plug-and-play integration with snap-in hook interlocking system Locating pins of the device cover lie directly beneath each recess of the antenna Snap-in hooks at the sides of the antenna snap into a matching set of apertures at the inner ends of the device cover Locating pins of the device cover fit snugly into the recesses of the antenna mobile device cover Figure 2. Alignment and interlocking features of the antenna and mobile device cover Figure 3. Easy integration of the Mobile TV Antenna into a mobile device cover

6 Features and Benefits Simple 50-ohm passive antenna interface Internal antenna design Specially-designed housing slots Vertical rib housing support RoHS compliant and halogen-free Complete CMMB band coverage without the need for costly active circuitry, switches or controls Reduced engineering costs due to simple interface between antenna and CMMB receiver Enhances mobile device appearance when integrated Eliminates concerns over durability and functionality of external antennas Hollowing-out of plastic material reduces the antenna s radiation loss Reduces antenna warpage during molding Environmental sustainability

7 Markets and Applications Telecommunications Mobile phones Smartphones Tablet PCs Notebooks and netbooks Mobile phones and smart phones Other Markets GPS navigation devices with CMMB functionality Other CMMB-enabled devices Tablet PC Notebook PC CMMB-enabled device
