We present a study of the multiwavelength properties of high-frequency peaked (HFP) radio sources. The study involved the simultaneous RATAN-600 measurements at frequencies of 1.2, 2.3, 4.7, 8.2, 11.2, and 22.3 GHz in 1997-2024, the RT-32 measurements at 5.05 and 8.63 GHz (IAA RAS), the RT-22 data at 36.8 GHz (CrAO RAS), and the literature data. It was found that the variability of the synchrotron emission of HFP sources is relatively low, it reaches 0.02-0.23 on the monitoring time scale of 17-27 years. Modeling of the broadband radio spectra of HFP sources shows that they can be satisfactorily described both by synchrotron self-absorption and by free–free absorption. For two of the sources, PKS 1614$+$051 and PKS 2126$-$158, we calculated the evolution of the synchrotron self-absorption spectrum parameters and the magnetic field strength. The results of the optical spectroscopical study of PKS 1614$+$051 and PKS 2126$-$158, performed with the SCORPIO-1 spectrograph at the 6-meter telescope, revealed that they have different internal structures and are located in different galactic environments.
