Indoor SSPA and HPA Systems

Question 1

Answer

The Indoor Systems range includes Indoor SSPAs (3RU, 5RU, 6RU, and 7RU rack-mount GaN and GaAs chassis), Indoor/Outdoor SSPA Systems (1:1 and 1:2 redundant and phase-combined configurations), and Indoor PowerMAX Systems (patented modular N+1 phase-combined HPAs scalable from 4 to 16 chassis).
GaN chassis cover L, S, C, X, and Ku bands with output power from 100 W to 1.7 kW per chassis. Indoor PowerMAX GaN 16-module configurations reach 10,000 W in C and X bands.

Question 2

Answer

Indoor PowerMAX is a patented (US Patent Nos. 8,189,338 B2 and 8,411,477 B2) modular N+1 phase-combined HPA where complete 3RU SSPA chassis serve as the module element.
Parallel redundancy extends to RF modules, power supplies, cooling fans, and embedded controllers simultaneously, enabling verified five-nines system availability.
Systems scale from 4 to 16 chassis modules without replacement and operate as a single logical amplifier on any M&C interface.

Question 3

Answer

1:1 redundant systems provide one standby chassis per online unit. 1:2 systems provide two standby units for full output power redundancy.
Phase-combined 1:1 and 1:2 systems add soft-fail fault tolerance alongside increased aggregate output power.
Indoor PowerMAX provides N+1 modular redundancy across all active assemblies for the highest availability tier.

Question 4

Answer

3RU, 5RU, 6RU, and 7RU chassis sizes are available in GaN and GaAs technologies.
GaN 3RU reaches to 800 W in L, S, C, and X bands and to 600 W in Ku band. GaN 7RU reaches to 1.7 kW C-Band, to 1.2 kW X-Band, and to 1.0 kW Ku-Band.
GaAs chassis provide C-Band and X-Band coverage for legacy system compatibility.

Question 5

Answer

RS-232 and RS-485 serial control plus Ethernet with SNMP, UDP, and internal web browsing are standard on all indoor chassis.
Front panel color touchscreen display with fault condition indicators and Local/Remote status is included on all units.
Form C contact alarms, opto-isolated inputs, and discrete hardware control are standard for site control integration.

Question 6

Answer

Indoor SSPAs are standalone rack-mount chassis for equipment room installation, available in single-unit or paired configurations.
Indoor/Outdoor SSPA Systems are fully integrated 1:1 and 1:2 redundant or phase-combined system configurations with controller and switching architecture included, built from any combination of indoor chassis.
The system configurations provide turn-key redundancy including waveguide switching, system controller, and all cabling.

Question 7

Answer

All indoor SSPA chassis use a separate external 1RU N+1 redundant hot-swap power supply with one more supply module than is required to operate the SSPA.
Single module failure does not affect HPA operation. Modules are hot-swappable at the front panel without taking the HPA offline.

Question 8

Answer

All indoor rack-mount SSPA chassis are rated for 0 to +50 deg C ambient temperature.
Relative humidity: non-condensing to 95 percent. Cooling is integrated forced air.
