Electrical Interface 9.1 Host Interface The host PCB requires the mating connector which is IPEX MHF (UFL) receptacle. The location should be close to the chip/modules pin for the RF. Any feed from this receptacle should be maintained at 50Ω impedance. 9.2 Transmission Line All transmission lines should be designed to have a characteristic impedance of 50Ω. • The length of the transmission lines should be kept to a minimum • Any other parts of the RF system like transceivers, power amplifiers, etc, should also be designed to have an impedance of 50 Ω Once the material for the PCB has been chosen (PCB thickness and dielectric constant), a coplanar transmission line can easily be designed using any of the commercial software packages for transmission line design. For the chosen PCB thickness, copper thickness and substrate dielectric constant, the program will calculate the appropriate transmission line width and gaps on either side of the feed. A DC blocking capacitor should be placed in line to protect the RF front end. 10. Mechanical Fixing The antenna uses 3M 468MP adhesive on the reverse side of the FPC. The antenna has an easy access split line to peel off to reveal the adhesive side. It is designed for a one time fix to a clean smooth surface.

However placement still needs to follow some basic rules, as any antenna is sensitive to its environment. Using six spatial directions shown below as a guide. The antenna FPC section should try to maintain a minimum of three directions free from obstructions to be able to operate effectively. The other directions will have obstacles in their paths, these directions still require a minimum clearance. These minimum clearances are further defined in this section. The plastic case is not included in this, only metal objects/components that will obstruct or come in close proximity to the antenna.

The proximity of the GND will have an influence on the antenna so the PCB location relative to the antenna should be considered. The FPC will normally be placed in one of the three following options for orientation. In each option a distance (d) is the critical dimension to consider. Below shows the minimum value of (d) for each. Other obstructions may increase this dimension. 1) Vertical mounted FPC Cable +Connector d ≥ 2mm PCB 1) Co-planar to PCB d ≥ 15mm 2) Planar to PCB (Same plane) d ≥ 2mm 10.3 Host PCB size SRFC011 is designed specifically for smaller devices. The host PCB size has a large effect on the performance. It is recommended for the host PCB to be
