762 MHz to 776 MHz and 850 MHz to 870 MHz
757 MHz to 758MHz
927 MHz to 941MHz
* Note that these frequencies have reached end-of-life, and whilst currently supported, are no longer available for
the TB9300. They are available for the TB9400, where B2 and B3 bands can be replaced by the B1 band.
Frequency increments
B and C bands
G4, H, K and L2 bands
2.5 kHz and 3.125 kHz
5 kHz and 6.25 kHz
Frequency stability
±0.5 ppm –30°C to +60°C (–22 °F to +140 °F)
a. For K band (700 MHz), the internal frequency reference accuracy is inadequate, and an external reference must be
used. The stability of this reference should be better than 100 parts per billion. See
