Baluns / Transformers

Product Description

IPDiA baluns have been specifically designed for space-constrained and for performances demanding applications in the GSM, DCS, WCDMA, WLAN (WiFi™) and WiMax frequency ranges.
Thanks to IPDiA’s proprietary IPD technology, IPDiA baluns offer a 50% gain in footprint compared to non-silicon solutions

Key Benefits

• Extremely low insertion loss
. 0.5dB (typ) for dual-band WiFi™
. 0.75dB (typ.) for DCS & WiFi™
. 0.95dB (typ.) for GSM & WiMax
• Return loss >12dB
• Smaller than SMDs
• Directly attachable on PCB by wire bonding with Chip On Board (COB) or flipped on PCB by standard reflow assembly
• High Temperature stability
• High reliability
