Tiga Device Guide
As 5G/mmWave (24–43 GHz) and GaN/GaAs devices pushed for higher power and efficiency, the need for real-time, wide-impedance-range, harmonic-capable synthesis became acute.
For decades, engineers used mechanical impedance tuners (slide-screw tuners) to synthesize load impedances for a DUT (Device Under Test). These passive tuners: tiga device
The Tiga device is an . Instead of mechanically reflecting the incident wave, it synthesizes the reflected wave ($b_2$) by measuring the outgoing wave from the DUT ($a_2$) and feeding back a coherent, phase-controlled signal back into the DUT’s output. As 5G/mmWave (24–43 GHz) and GaN/GaAs devices pushed
With electronic settling time in microseconds, the Tiga device can hop between impedance states faster than the symbol rate of a 100 MHz 5G signal, enabling dynamic load-pull —measuring EVM vs. instantaneous impedance trajectory. Instead of mechanically reflecting the incident wave, it
One of the most direct commercial uses of the name is the . This specialized health tool is designed for individuals suffering from positional sleep apnea or heavy snoring.
Why "Tiga"? It is a backronym: ime-domain I njection G enerator for A ctive load-pull. But more poetically, "Tiga" is the Malay/Indonesian word for three —a subtle nod to the three-wave interaction (incident, reflected, injected) or the three domains (frequency, time, modulation) the device bridges.
