Description

The F6503 is an 8-channel transmitter (TX) silicon IC designed

using a SiGe BiCMOS process for CDL phased array applications.

The core IC has 360° 6-bit phase control coupled with 35dB 6-bit

gain control on each channel to achieve fine beam steering and

gain compensation between radiating channels. The device has a

25dB nominal gain and 13dBm OP1dB. The core chip achieves an

RMS phase error of 3° and an RMS gain error of 0.4dB over the

frequency of operation. The typical total power consumption is

1.4W (175mW per channel) at OP1dB.

Competitive Advantage

 High integration

 Orthogonality of phase and amplitude control

 Advanced Serial Peripheral Interface (SPI) with 4 state

memory

 Superior channel-to-channel isolation

 Minimal footprint

Typical Applications

 CDL Terminals

 Aerospace and Maritime

 Beam Steering

 Point-to-Point (Line-of-Sight) Communications
