NOTES:
# RAM-8(+) input and output impedances are not 50 ohms, see S-parameter data. Conditionally stable, source
and load VSWR<3:1 required. RAM-6(+) conditionally stable, source and load VSWR<5:1 required.
1. Minimum gain at highest frequency. Full temperature range, except roomtemperature for RAM-4(+) models.
2. Low frequency cutoff determined by external coupling capacitors.
3. Frequency at which output power, NF and IP3 are specified: 500 MHz for RAM-4(+), 1000 MHz for all other models.
4. RAM-6(+) potentially unstable with very high VSWR terminations.
5. Thermal resistance
jc is from hottest junction in device to mounting surface of leads.
6. Permanent damage may occur if any of these limits are exceeded. These ratings are not intended for continu-
ous normal operation.
7. Supply voltage must be connected to pin 3 through a bias resistor in order to prevent damage. See "Biasing
MMIC Amplifiers" in minicircuits.com/application.html. Reliability predictions are applicable at specified current
& normal operating conditions.
