Pick Hit 2009: Flexiva HPX™
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
