GSM/3G Penta Band Hybrid PCB Antenna Pulse Part Number W3544A / 3544B Pulse introduces the small hybrid surface mount pickand-place W3544X family of GSM/3G antennas. Board connection is via 6 SMD connection points underneath the antenna. Antennas are delivered in tape and reel packaging for use in automatic SMD pick-and-place. Each antenna measures 7.65 x 26 x 3 mm and requires ground clearance on the PCB. The W3544A is optimized for a corner board location while the W3544B is for use at the end of a narrow PCB. Frequency bands are 824960 and 1710-2170 MHz with a target of minimum 50% efficiency in all bands offering a compact high performance solution for GSM/3G applications Features - Frequency bands 824-960 and 1710-2170 MHz - SMD solution - Compact antenna size of 7.65 x 26 x 3 mm - RoHS Compliant Product Applications - GSM/3G routers - Femto Cell modems - Industrial wireless machine to machine - Smart Grid devices - Mobile Hotspots San Diego, CA 858 674 8100 Part Number Positioning W3544A Vertically mounted at board edge W3544B Horizontally mounted at board edge Vancouver, WA 360 944 7551 1 Europe 49 7032 7806 0 Asia 86 755 33966678 pulseelectronics.com/products/antennas North Asia 886 3 4356768 China 86 512 6807 9998 L143.A (02/13) GSM/3G Penta Band Hybrid PCB Antenna Pulse Part Number W3544A / 3544B Electrical Specifications W3544A W3544B Frequency 1 [MHz] 824 - 960 824 - 960 Frequency 2 [MHz] 1710 - 1880 1710 - 1880 Frequency 3 [MHz] 1850 - 1990 1850 - 1990 Frequency 4 [MHz] 1920 - 2170 1920 - 2170 50 50 Return Loss Gain Nominal Impedance [] Freq 1 [dBi avg] -1.9 65% -1.5 70% Freq 2 [dBi avg] -1.3 74% -1.1 77% Freq 3 [dBi avg] -1.3 74% -1.1 77% Freq 4 [dBi avg] -1.66 68% -1.5 71% Frequency 1 [dB] -4.1 -6.5 Frequency 2 [dB] -4.6 -5.7 Frequency 3 [dB] -16.3 -18.5 Frequency 4 [dB] -12.3 -13 Note: Gain: Frequency detail above is all peak and given in dBi first, then efficiency.
