OEMV RF Input sensitivity

The following levels at the receiver board input are acceptable (for tracking):

1. L1 signal power at board input *-122 to -87 dBm*, noise power at board input -161 to -141 dBm/Hz OEM design guidance: C/No range at board input 35 to 58 dBm/Hz

2. L-band signal power at board input -125 to -102 dBm, noise power at board input -161 to -151 dBm/Hz OEM design guidance: C/No range 31 to 53 dBm/Hz

The OEMV receiver series are designed to work with the following antenna/cables limits:

                        Antenna LNA-Antenna  Gain Cable

Gain Nom (dB) 26.00                            -6.00

Gain Max (dB)  30.00                            -0.05

Gain Min (dB    22.00                            -10.00

Reference Input Impedance (ohm) 50 50

Notes:

1. Antenna gain includes antenna element and LNA.

2. For most cases, the signals are buried under the receiver noise floor.

3. Pre-receiver gain for L-band case should be treated with care given the signal could be above the noise, and the receiver can be over-driven due to the strong signal amplified by higher gain before receiver.

4. Receiver potential performance will be degraded if the input conditions are not met.|
