The number 325 can refer to several different things, depending on the context. It could be a frequency in Hertz (Hz), a frequency in kilohertz (kHz), or a frequency in gigahertz (GHz). It could also refer to a specific frequency range, like 325 kHz in the maritime radionavigation service. Additionally, 325 could be part of a larger frequency range, such as 280-325 GHz.
Here's a breakdown of how 325 can be associated with different frequencies:
Frequencies in Hertz (Hz):
325 Hz Binaural Beat: This frequency is used in binaural beats to induce relaxation and potentially a deep sleep, according to one source.
325 kHz Range: The band 315-325 kHz is used in the maritime radionavigation service for transmitting supplementary navigational information.
Frequencies in Gigahertz (GHz):
325 GHz Frequency Multiplier Chains: Several research papers discuss frequency multiplier chains operating around 325 GHz, often in the context of SiGe HBT technology.
325 GHz Doublers: These are circuits designed to double the frequency of an input signal, with examples being developed for operation up to 325 GHz.
325 GHz Balanced Frequency Tripler: Research papers detail a balanced frequency tripler operating up to 330 GHz.
325 GHz Amplifier Chain: Research papers detail a 300 GHz amplifier chain with a 280-325 GHz bandwidth.
325 GHz Signal Analyzer Module: Keysight offers a millimeter-wave signal analyzer frequency extension module that covers the 325 to 500 GHz range.
Key Research Areas
SiGe HBT Technology: Much of the 325 GHz doubler research utilizes Silicon-Germanium (SiGe) Heterojunction Bipolar Transistor (HBT) technology, leveraging high cut-off frequencies (fT/fmax) for these applications.
Multiplier Chains: Researchers have built 325 GHz multiplier chains, often including cascaded triplers, to generate the 325 GHz output signal from lower frequency inputs (e.g., 18 GHz).
Transformer-Based Designs: Transformer-based baluns and circuits are used to convert single-ended input signals into differential signals for balanced doubler operation, improving performance and efficiency.
Balanced Doublers: Balanced doublers are employed to improve power and suppress unwanted harmonic frequencies, enhancing the quality of the output signal.
High Output Power & Efficiency: Studies focus on achieving high saturated output power (Psat) and high conversion gain (CG), as well as improving DC-to-RF efficiency.
Wideband Operation: Research also targets wideband doubler designs, with efforts to achieve high output power over a broad frequency range, such as 268-325 GHz.
Examples of Research
Transformer-Based Doubler: One research effort focuses on a transformer-based frequency doubler for radar applications, achieving 5.2 dBm saturated power between 268 and 325 GHz.
Balanced Doubler with Balun: Another paper details a balanced frequency doubler in a 130 nm SiGe BiCMOS technology that achieves 6.5 dBm peak output power at 204 GHz using an on-chip transformer balun.
Multiplier Chain: A single-chip 325 GHz multiplier chain was presented, consisting of two cascaded triplers and a balanced output doubler, operating from 317 to 328 GHz with a 0-dBm 18-GHz input signal.
These advancements are critical for applications in areas such as radar and high-frequency communication, pushing the boundaries of silicon-based devices into the terahertz (THz) range.

I think both the U.S. and Russian agencies knew of deep space signals.

A matter of EXTREME GRAVITY.
