Today’s wireless products juggle multiple cellular bands alongside 5 GHz traffic for backhaul and throughput. That mix only works when signals are cleanly routed, losses stay low, and each path is shielded from its neighbors.

LQD-2520-DHNKA-A1 solves this need in a single 2520 LTCC quadplexer that combines/separates four paths – LB, MHB, UHB, and 5 GHz (LAA) through a single 50-Ω common port. It trims PCB area and tuning time while delivering low in-band loss, deep out-of-band rejection, and a straightforward pad map for fast layout.

Package Size: 2520 (2.50 × 2.00 × 0.55 mm), 9 pads

Ports/Bands: LB 617–960 MHz; MHB 1450–2690 MHz; UHB 3400–3800 MHz; LAA 5150–5925 MHz

Typical Insertion Loss: LB ~0.94 dB; MHB ~1.19 dB; UHB ~0.93 dB; LAA ~0.69 dB

Band-to-Band Rejection: up to ~46 dB typical (pair-dependent)

In-Band Match: ≥10 dB return loss (typ. ~13–16 dB) with 50-Ω ports

Construction: LTCC; tape-and-reel; reflow compatible

One common-port part replaces multiple discrete filters/diplexers. That reduces the BOM count and frees PCB area, and it also speeds time to certification. RoHS compliant, and compatible with automated pick-and-place, LQD-2520-DHNKA-A1 suits high-volume mobile, industrial, and consumer platforms.
