High Dynamic Range, 75Ω Dual MMIC Amplifier, 40 MHz to 1.25 GHz


Product Overview MPGA-122-75+ (RoHS compliant) is an advanced wideband dual amplifier fabricated using E-PHEMT* technology and offers extremely high dynamic range over a broad frequency range and with low noise figure and flat gain. In addition, the MPGA-122-75+ has excellent input and output return loss when used per suggested application circuit over a broad frequency range. It is enclosed in a 4x4mm, 24 lead MCLP package for very good thermal performance. Feature Advantages Broad Band: 0.04 to 1.25 GHz Usable to 1.5 GHz Covers primary CATV applications such as DOCSIS 3.1 Positive Gain Slope, 0.3 dB Compensates for increasing loss versus frequency of cables High IP3 Versus DC power Consumption: 51 dBm typical at 0.5 GHz The MPGA-122-75+ matches industry leading IP3 performance relative to device size and power consumption. The combination of the design and E-PHEMPT structure pro- vides enhanced linearity over a broad frequency range as evidence in the IP3 being typically 14-19 dB above the P 1dB point. This feature makes this amplifier ideal for use in CATV applications. High IP2, 68 dBm at 0.5 GHz Suppresses second order product on wideband applications such as CATV Low Noise Figure, 2.8 dB at 0.5 GHz Low noise figure performance in combination with the high output IP3 results in high dynamic range. Excellent CSO/CTB* CSO, -80 dBc CTB, -83 dBc Measured at channel 17 Competitive performance at lower current and supply voltage. MPGA-122-75+
