Fujikura's own True-Time-Delay system has allowed PAAM to control the gain and phase of signals individually and also brought some distinctive features as listed below. For example, the module can emit a beam at a desired angle by a simple calculation without calibration. This makes it possible to direct the beam at a target to communicate instantly without any blind spots.

Phased Array Antenna Module (PAAM)

• Benefits customers by offering optimal TCO and reducing development time • Is available as complete module containing BFIC, FCIC, filter and antenna • Operates at 24-30 GHz and covers n257, n258 and n261 • Is highly integrated to support concurrent dual-polarization for Tx/Rx

Calibration- free operation

• Enables easy digital setting for prescribed performance by individual gain/phase control • Eliminates the need for individual calibration

Low signal distortion in beam directions

Maintains beam shape in beam directions and wide frequency range by True-Time-Delay phase shifter

Superior digital reconstruction

Allows flexible trade-off between NF and linearity

Low ACLP

RF filtering with high-Q on-board filter

High-precision, high-resolution beam steering control by True-Time-Delay-Type phase shifters

Supports ultra-fast access in 65,536 beam directions by advanced on-chip calculation mode. Fujikura PAAM provides a high-quality communications environment with no dead spots throughout base stations area by accurate beamforming.

Sufficient TX output power required of base stations with high efficiency and low-power consumption

Fujikura PAAM simplifies the thermal management of base stations, therefore enables miniaturization and cost reduction.

Flexible tuning for the noise figure and linearity of receiver

Fujikura PAAM enables flexible settings depending on various location conditions of base station from macrocell to microcell.

Supporting dual polarization in both transmission and reception

Fujikura PAAM transmits and receives the signals in both horizontal and vertical polarization. This contributes to miniaturization and cost reduction of base stations.
