Encyclopedia > L Band

L band (20-cm radar long-band) is a portion of the microwave band of the electromagnetic spectrum ranging roughly from 0.39 to 1.55 GHz. It is used by some communications satellites, and by terrestrial Eureka 147 digital audio broadcasting. In the U.S., the L band is held by the U.S. Military for telemetry, thereby forcing digital radio to in-band on-channel (IBOC) solutions. DAB is typically done in the 1452–1492-MHz range as in Canada, but other countries also use VHF and UHF bands.


The Global Positioning System carriers are in the L band, centered at 1176.45 MHz (L5), 1227.60 MHz (L2), 1381.05 MHz (L3), and 1575.42 MHz (L1) frequencies.


The different NATO "L band" is defined as frequency band between 40–60 GHz (5–7.5 mm).

LRX-MOD1 - L Band Receiver - PMC Front Panel Mezzanine Module (457 words)
The L band is a portion of the microwave section of the electromagnetic spectrum ranging from 950 - 2150 MHz.
Global Positioning System carriers are also in the L band, centered at 1176.45 MHz (L5), 1227.60 MHz (L2), 1381.05 MHz (L3), and 1575.42 MHz (L1) frequencies.
The LRX-MOD1 uses a MAX2118 device to directly convert L band signals to baseband using a broadband quadrature (I/Q) downconverter.
Radar Bands (528 words)
L band radars operate on a wavelength of 15-30 cm and a frequency of 1-2 GHz.
L band radars are mostly used for clear air turbulence studies.
The drawback to this band of radar is that it requires a large antenna dish and a large motor to power it.
