Flexiva HPX™

High-Power Transmitter for Analog FM and HD Radio™

OVERVIEW

The Flexiva HPX series is the next generation in high-power transmission for FM analog and HD Radio™ broadcasting. The Flexiva HPX series covers a range of power levels, with three models offering nominal FM power of 20 kW, 30 kW and 40 kW in a single configuration, and up to 80 kW in a dual configuration.

With the most flexible control system available in the market, the Flexiva HPX transmitter has a unique combination of dedicated meters and control circuits for rock-solid and simple control, coupled with an optional user-friendly remote monitor and control system that features a color GUI.

In terms of dollars-per-watt, the Flexiva HPX tube-based transmitter outperforms all solid-state transmitters in the same class. Operators can realize a significant savings in cost of ownership over the lifetime of the transmitter, including regular tube replacement.

The Flexiva HPX transmitter provides a smooth upgrade path to HD Radio. Simply add the FlexStar® HDx exciter and the HDE-200 exporter for the latest in HD Radio signal generation, and if desired, the HDI-200 importer will complete the portfolio with supplemental audio channels and other advanced applications data services.

GatesAir provides everything needed to transition to digital radio — from source through studio through STL through transmission. And we have a systems team available to help put together a package that makes the most sense for any operation — now and in the future.

Main Features of Flexiva HPX™

The Flexiva HPX high-power FM transmitters feature:

Fully integrated RF and control interface with FlexStar® exciters
The FlexStar HDX exciter is the source of both the HD Radio signal and the conventional analog FM signal — in a single unit. This exciter creates a hybrid signal ready for amplification by the transmitter
High-voltage power supply can be remotely located from the transmitter to fit even the tightest transmitter sites
Basic transmitter controller provides critical life support, control, automatic exciter switching and diagnostic functions on MIMIC panel without reliance on a microprocessor
Advanced transmitter controller option combines basic controller functionality and life support with a microprocessor and ¼ VGA GUI for advanced control and diagnostics including TCP/IP connectivity, WEB remote control and monitoring, and SNMP communications
IPA stage uses the field-proven Z/ZX® hot-pluggable PA modules and power supplies with the option for redundancy
¼ wave grounded cathode design offers stability and efficiency
Ability to bypass PA stage using Flexpatch to put exciter and/or IPA directly to air, with blower shut down. No user safety issues while servicing PA cavity
Backed by broadcasting’s most extensive factory support, including 24-hour technical assistance, around-the-clock parts and comprehensive training

System

High-power FM/FM+HD tube-based transmitter with nominal nameplate (FM) power output rating based on three models of 20 kW, 30 kW and 40 kW

Mechanical

Solid, welded-steel exterior cabinets; aluminum inner skins and chassis
Hinged rear doors for normal access, easily removed for maintenance or installation activities
Major access panels are securely latched with a supplied hex head tool for quick, safe access
Top- or bottom-entry locations for all cabling

Cooling

Direct drive 3-phase blower in main PA cabinet
High-efficiency flushing fans

RF Drive

Requires only 30 W (analog) exciter
Fully integrated RF and control interface with FlexStar exciters
IPA stage uses the field-proven Z/ZX PA modules
- Higher-power models employ two modules, providing redundancy
- Lower-power system can employ optional main/backup IPA
IPA modules are replaceable from the front of the transmitter

Power Amplifier Stage

Common tube socket for all models; 4CX20,000C
¼ wave grounded cathode design offers stability and efficiency
Ability to bypass PA stage using Flexpatch to put exciter and/or IPA directly to air, with blower shut down. No user safety issues while servicing PA cavity

Controller

Basic transmitter controller provides critical life support, control, automatic exciter switching and diagnostic functions on MIMIC panel without reliance on a microprocessor
Enhanced transmitter controller option combines the basic controller functionality and life support with a microprocessor and ¼ VGA GUI for advanced control and diagnostics including TCP/IP connectivity, WEB remote control and monitoring, and SNMP communications
Four large front-panel analog meters: Forward/Reflected power, PA volts, PA amps and multimeter for other operating parameters

Power Supplies

High-voltage, 3-phase linear supply with primary/secondary MOV protection; half tap on transformer and multiple voltage taps; some model upgrades may be accomplished with only change in HV transformer
Rugged, reliable mains transformer provides worry-free performance, easy to tap for specific installation requirements
Low-voltage control and IPA use switching supplies from field-proven ZX products, reducing spare parts costs
