4. 2 x RF Board – Each board consists of single transmit/receive module that modulate the
analog WiMAX signal input from the Base-Band modem to the high frequency RF
output. Several RF modules exist - each supporting different frequency band.
5. 2 x PA Board – Power Amplifier module that amplifies the RF signal from the RF output
to the desired transmit output power. Several modules exist, supporting the different
frequencies and several transmit levels.
6. Power Supply – DC/DC power supply. Converts the 48VDC to the various voltages that
are feeding the Digital and the RF modules.
7. Chassis: 140W power dissipating aluminum box.
8. Antennas: Two Antennas to support the schemes. Several antennas option exists (e.g.
External 65/90/120 Sectors, Integral Omni).
