The phrase "a substantially high frequency" is correct and usable in written English.
It can be used in contexts discussing measurements, signals, or occurrences that are notably elevated in frequency compared to a standard or baseline.
Example: "The device operates at a substantially high frequency, allowing for faster data transmission."
Alternatives: "a significantly high frequency" or "an elevated frequency".
Cells cultured on substrates with smaller pitches exhibited a substantially higher frequency of cell alignment and smaller circularity index.
Self-fertilized eggs develop with a substantially higher frequency of anomalies during cleavage than cross-fertilized eggs (23% vs. 1.6%).
Thus, the BrdU studies using diabetic mice support the conclusions drawn using DNA content determination; i.e. compared to mice with normoglycemia, diabetic mice have a substantially higher frequency of BrdU+ β-cells (9-fold).
We experienced less sequencing and alignment problems for atpF atpH than the other non-coding regions; i.e., it has a substantially higher frequency of bidirectional reads, fewer sequencing reads per amplification product, and (compared to trnH-psbA) fewer micro-inversions.
The MICA-A9 triplet repeat polymorphisms were present at a substantially higher frequency in PsA patients [ 60].
EAs are therefore expected to have a substantially higher frequency of rare homozygotes than AAs – 0.006 vs. 0.002, i.e. about three times as many.
In contrast, patients who identified themselves as belonging to any other ethnic group had a substantially higher frequency of discordant HES-recorded ethnicity (41.2% (39.7 42.7%)).
Nuclear DNA 8-oxoG damage was significantly higher in HIV + patients, particularly those with HAND, and a substantially higher frequency of noncoding D-loop mutations in mtDNA among HAND cases was noted as compared with either HIV + or seronegative controls.
In conclusion, our data suggest that a larger fraction of expecting women are vulnerable to potential TCS- and TCC-induced health outcomes compared to the general United States population due to a substantially higher frequency and extent of exposure.
Even for satellite communication norms, the Ka band is substantially higher frequency than the Ku band used by many satellites today.
