spe - 12 - 8 - 126/ b /ez page 2 of 17 1. introduct ion th e warrior, the revolutionary paten t pending pa.710 a is a 2g/3g/4g , high ef ficiency smt ce ramic antenna, operating at 698mhz to 960mhz and 1710mhz to 2690mhz . it uses high grade custom ceramic material and new design techniques to deliver the highest efficiencies on all bands when mounted on the devices main pcb. the exceptional wide - band response means it is the ideal antenna for all lte applications that also need high efficiency and backward compatibility for 2g and 3g globa lly on all lower and upper bands. the pa.710 a is delivered on tape and reel and mounted securely during the device pcb reflow process . 1 .1 key advantages 1. highest efficiency in a small size , i.e. 40m m*6mm*5mm. a comparative antenna , for example metal/fr4/fpc/whip/rod/ helix , would h ave much reduced efficiency in this configuration due to their different dielectric constants. very high efficiency antennas are critical to 3g and 4g devices ability to deliver t he stated data - speed rates of systems such as hspa and lte. 2. more resistant to detuning compared to other antenna integrations. if tuning is required it can be tuned for the device environment using a matching circuit , or other techniques on the main pc b itself . there is no need for new tooling, thereby saving money if customization is required. 3. highly reliable and robust C its p redecessor s the pa.25 a and pa700 a antennas are used by the worlds leading auto motive makers in extremely challenging envir onments. the antenna meets all temperature and mechanical specs required (vibration, drop tests etc) 4. easy to integrate . other antenna designs come in irregular shapes and sizes making them more difficult to integrate. 5. surface mount technology ( directly on - board) antenna saves on labor, cable and connector costs, leads to higher integration yield rates, and reduces losses in transmission. 6 . minimum transmission and reception l osses - these are kept to absolute minimum resulting in much improved ota (over the air ) , i.e. trp (total radiated power)/tis (total isotropic radiation) , device performance compared to similar efficiency cable and connector antenna solutions . this means it is an ideal antenna to be used for devices that need to pass for example usa carrier network approvals 7 . rse reductions C will help to eliminate radiated spurious emission failures compared to other antenna technologies as the required layout for the antenna can deliver natural isolation between the onboard noise and the antenna itself. also the antenna can be matched better to the system with the matching circuit function.
spe - 12 - 8 - 126/ b /ez page 3 of 17 8 . high gain in both polarization planes - achieves moderate to high gain in both vertical and horizontal polarization planes. this feature is very useful in certain wireless communications where the antenna orientation is not fixed and the reflections or multipath signals may be present from any plane. in those cases the important parameter to be considered is the total field strength, which is the vector sum of the signal from the horizontal and vertical polarization planes at any instant in time. 2. specification electrical antenna pa710 warrior standard 2g/3g/4g operation frequency (mhz) 698~960mhz 1710~2170mhz 2300~2400mhz 2490~2690mhz peak gain 1.0db i 3.2dbi 3.5dbi 3.5dbi average gain - 2.3 db - 1.5db - 1.8db - 1.5db efficiency 60% 70% 65% 70% vswr <3.0:1 impedance 50? ? the warrior pa710 antenna per formance was measured with 120 x45 mm ground plane. mechanical dimensions (mm) 40 x 6 x 5 mm material ceramic termination ag (environmental - friendly pb free) evb connector sma - female environmental operation temperature - 40c to 85c storage temperature - 40c to 105c relative humidity non - condensing 65c 95% rh rohs compliant yes
