surface mountable dielectric chip antennas ahd1403-244st series mar- 2001 advanced products company 2 / 2 mitsubishi materials corporation 6. series of center frequencies(f 0 ) in case of surface mount antennas, the center frequency is dependent on the pcb size or other surrounding components and materials, and therefore can be different from what is measured with our standard test board. for the ahd1403-244st, we have therefore prepared series of items having different center frequencies with a certain frequency step, in order to cancel the above mentioned frequency shift by the environmental factors. so with our ahd1403-244st series, you can easily and quickly find the most suitable antenna for your own mounting conditions. example 1: if you take the ahd1403-244st 01 (nominal f 0 =2440mhz), but see that the center frequency is 2490mhz ( 50mhz higher ) when mounted on your own board : we recommend to use ahd1403-244st 25 (nominal f 0 =2390mhz, d f 0 =-50mhz). example 2: if you take the ahd1403-244st 01 (nominal f 0 =2440mhz), but see that the center frequency is 2 35 0mhz ( 9 0mhz lower ) when mounted on your own board : we recommend to use ahd1403-244st 10 (nominal f 0 =2530mhz, d f 0 =+90mhz). 7. custom design in addition to the ahd1403-244st series, we are also doing custom designs with various sizes and frequencies. please feel free to contact us for details. examples of custom products type sizes operating frequency range operating temperature application look ahd1206-244st01 12 6 0.64mm 2400mhz | 2484mhz -25 c | +85 c wireless lan bluetooth apd1008-244st01 10 8 4mm 2400mhz | 2484mhz -25 c | +85 c wireless lan bluetooth apd1512-244st02 15 12 2mm 2400mhz | 2484mhz -25 c | +85 c wireless lan bluetooth APD1512-244ST01 15 12 4mm 2400mhz | 2484mhz -25 c | +85 c wireless lan bluetooth note: 1) the specifications given herein may be changed or modified at anytime without prior notice. 2) please request specifications for the part your plan to use. contact us : mmc electronics america inc. - chicago office 1365 wiley road, suite #149, schaumburg, il 60173 tel :1-847-490-0222 fax:1-847-490-0218 email: sales@mmea.com mmc electronics america inc. - san jose office 45 east plumeria dr., san jose, califonia 95134 tel :1-408-571-2001 fax:1-408-571-209
