The new HL5810 15GHz Limiting Amplifier is a is a thermally-compensated design which was intentionally developed for broadband pulse amplification and NRZ data transmission up to 20Gbps.

Model HL5867 is a single stage, GaAs MMIC traveling wave amplifier (TWA) providing 13 dB gain from 75 kHz to 30 GHz. For use as a data driver, the HL5867 was designed for 32 Gbps NRZ and PAM4 data signaling.
