The IBUC 2 is a compact integrated BUC/GaAs SSPA designed for higher performance & reliability. Block Upconverters based on linear GaAs amplifier technology require minimal output power backoff. 24-48-hour environmental chamber testing guarantees PI dB output power over frequency and temperature range. Multiple sensors & a new, high-capacity microprocessor provide tools to optimize terminal performance. The IBUC 2 is a popular choice for medium-high power Satcom terminals in telecom, defense, air traffic control, government & other demanding network applications.
