The TW2605 features a high performance dual-feed patch element that provides great axial ratio (3dB max) over the entire Iridium™ frequency band, thus signals at the band edges remain truly circular, unlike the response of single feed antennas. TW2605 Dimensions (mm) The TW2605 provides excellent Iridium™ signal coverage, and comes in a compact circular form factor with a built-in 50 mm diameter ground plane. Standard coax cable is 15cm of RG174. Custom tuning, cable length, and connectors are available on request. ## **Applications** - Iridium™ Voice and Data Applications - Sea & Land Container Tracking - Military & Security - Fleet Management & Asset Tracking - Marine & Avionics Systems - Law Enforcement & Public Safety ## **Features** - Custom high gain 4.25 dBic dual-feed patch - Great axial ratio, 3 dB over full bandwidth - 15 KV ESD circuit protection - Robust design ## **Benefits** - Excellent circular polarized signal transmission - Industrial temperature range - Rugged Design - RoHS compliant - Small form factor - Available application specific tuning ## TW2605 Embedded Iridium™ Certified Antenna ## **Specifications** Vcc = Over full bandwidth, T=25°C ## **Antenna** Architecture Antenna Gain (100mm ground plane) Axial Ratio (over full bandwidth) Radiated Bandwidth (-0.5 dB) Dual, quadrature feeds 4.25 dBic ≤3 dB 1605 MHz to 1635 MHz ## **Electrical** Architecture Frequency Bandwidth Polarization Cross Polarization Rejection Gain flatness VSWR (at antenna) Return Loss Bandwidth (10 dB return loss) ESD Circuit protection Hybrid 90° phase signal splitter 1616 to 1626.5 MHz RHCP typically 20dB ≤0.5 dB, from 1616 to 1626.5 MHz <1.5:1 >20 MHz 15 KV air discharge ## **Mechanicals & Environmental** Mechanical Size Cable Operating Temp.
