With 1 dB and 1.5 dB of noise figure in 75 Ω CATV, 5–1218 MHz and 50 Ω system, 5-2000 MHz respectively, unit provides adjustable 20-85 mA current and return loss of 23 dB. Amplifier is housed in SOT-89 plastic package.

Original Press Release:

Richardson RFPD Introduces New High-performance CATV Amplifier from MACOM

Versatile amplifier can be biased from 3 to 5 volts

Richardson RFPD, Inc. announced today the availability and full design support capabilities for a low noise amplifier for CATV applications from MACOM Technology Solutions Inc.

In a 75 Ω CATV application, the MAAL-011139 provides 21.5 dB of flat gain while biased from 3 to 5 volts. It provides superior noise figure while maintaining excellent return losses, and gain and current may be optimized with adjustment of external component values. The new device is assembled in a SOT-89 plastic package.

The MAAL-011139 is ideally suited as the input stage for fiber-to-the-home (FTTh) applications and other 75 Ω infrastructure applications. It can support upstream (5–204 MHz) and downstream (45–1218 MHz) CATV operation.

The MAAL-011139 can also be matched into a 50-ohm system. In a broadband 50–2000 MHz application, the LNA provides 17 dB of flat gain. It offers 17 dB of available gain beyond 4 GHz.

Additional key features of the MAAL-011139 include:

  • Single stage, single-ended
  • 75 Ω CATV, 5–1218 MHz
    • 21.5 dB flat gain
    • 1 dB noise figure
  • 50 Ω system, 5–2000 MHz
    • 17 dB gain
    • 1.5 dB noise figure @ 1.5 GHz
  • 17 dB maximum available gain @ 4 GHz
  • Adjustable current: 20–85 mA
  • Return loss: 23 dB
  • OIP3: +34 dBm
