RF Power Amplifier
Integrated PA stage adds link margin for extended stand-off range.
The K9-SAT-PA-001 is a long-range bugging device — the core transmitter with an integrated RF power amplifier, adding link margin for extended-range audio surveillance and difficult RF environments.
When the receiver must sit well outside the target area, link margin becomes the limiting factor. The K9-SAT-PA-001 answers that with an integrated RF power amplifier on the core transmitter, making it a long-range bugging device suited to stand-off deployments and challenging UHF environments.
It retains the full encrypted, frequency-hopping architecture — AES-128 voice over an FHSS link factory-set within 413–479 MHz or 826–958 MHz — so extended range comes without compromising the operational security that defines the range. Ideal for long-range audio surveillance where proximity is not an option.
Integrated PA stage adds link margin for extended stand-off range.
Designed for deployments where the receiver is far outside the target area.
Engineered for reliable operation in demanding UHF conditions.
FHSS preserved at extended range — no fixed carrier exposed.
Full encryption maintained regardless of transmit power.
Factory-set within 413–479 MHz or 826–958 MHz (covering 433, 458 and 868 MHz) — no field re-tuning.
The integrated power amplifier adds the link margin to monitor from a receiving position well outside the target area — for stand-off and vehicle-based operations where proximity is not an option.
Extra link margin holds the encrypted, frequency-hopping audio together through structures, distance and clutter that would break a standard-power covert transmitter.
