Product details
Overview
HMC400MS8TR from Analog Devices (formerly Hittite Microwave) is a high-dynamic-range passive GaAs MMIC mixer in an 8-lead MSOP package, operating from 1.7 to 2.2 GHz RF with 1.4–2.15 GHz LO and DC–300 MHz IF. It delivers +36 dBm input IP3 (downconversion), 8.5 dB typical conversion loss, 22–33 dB LO-to-RF isolation, +21 dBm P1dB, and requires no external bias or components-enabling compact GSM/UMTS infrastructure front-ends.
For engineers reviewing the HMC400MS8TR datasheet, HMC400MS8TR pinout, HMC400MS8TR application, or HMC400MS8TR equivalent, key selection criteria include its high IP3 at low LO drive (+17 dBm), single-ended 50 Ω matched ports, ultra-small 14.8 mm² footprint, and compatibility with low-side LO architectures in wireless base station transceivers and cable modem termination systems.
Technical Context
This monolithic passive FET mixer uses GaAs Schottky diode-based topology with integrated balun structures to achieve broadband RF/LO matching without external tuning. Its architecture supports both upconversion and downconversion modes, with distinct IP3 performance: +36 dBm (down) and +29 dBm (up) at +17 dBm LO drive.
It operates with fixed low-side LO injection and delivers flat IF response from DC to 300 MHz. All ports are DC-coupled except LO (AC-coupled), and thermal stability is maintained across −40°C to +85°C via optimized GaAs process design and MSOP thermal pad grounding.

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP3E | Wider RF range (1.5–3.5 GHz); higher conversion loss (9.5 dB typ); same MSOP-8 package. | Better suited for multi-band LTE infrastructure where extended frequency coverage outweighs 1 dB loss penalty. | Select HMC1040LP3E when RF band extends beyond 2.2 GHz and +35 dBm IP3 remains acceptable. |
| ADL5801ACPZ-R7 | Active mixer; +26 dBm IP3; requires +5 V bias; 24-lead LFCSP; 50–3500 MHz RF range. | Offers gain instead of loss but adds power, heat, and complexity; used where system NF demands active conversion. | Choose ADL5801ACPZ-R7 only when conversion gain is mandatory and DC power is available. |
Compared with HMC400MS8TR, HMC1040LP3E trades 1 dB higher loss for broader band coverage, while ADL5801ACPZ-R7 introduces DC bias dependency and larger package to deliver gain-making HMC400MS8TR optimal for low-power, high-linearity, passive-only 1.7–2.2 GHz infrastructure designs.

FAQ
What is the recommended LO drive level for optimal performance of the HMC400MS8TR?
The HMC400MS8TR achieves best-in-class +36 dBm input IP3 and 8.5 dB conversion loss at +17 dBm LO drive. Operation between +16 dBm and +18 dBm is supported; outside this range, IP3 degrades by ~1–2 dB per dB deviation. The datasheet specifies +17 dBm as the reference condition for all key RF specs including isolation and P1dB.
Does the HMC400MS8TR require external DC biasing or passive components for basic operation?
No, the HMC400MS8TR is a fully passive GaAs MMIC mixer requiring no DC bias voltage or current. Only two external components are needed for standard use: a DC-blocking capacitor on the LO port (Pin 1) and optional DC-blocking on the IF port (Pin 5) if DC operation is not required. All RF/LO/IF ports are internally matched to 50 Ω.
Can the HMC400MS8TR be used for both upconversion and downconversion, and how do specifications differ?
Yes, the HMC400MS8TR supports both modes. In downconversion (RF→IF), input IP3 is +36 dBm; in upconversion (IF→RF), it is +29 dBm-both measured at +17 dBm LO drive. Conversion loss remains ~8.5 dB in either direction, but LO–IF isolation drops to 16–25 dB in upconversion versus 22–33 dB LO–RF isolation in downconversion.
What is the thermal and mechanical mounting requirement for the HMC400MS8TR MSOP package?
The HMC400MS8TR MSOP package features an exposed thermal paddle that must be soldered to a solid PCB ground plane using multiple thermal vias. Pins 3, 6, and 7 are dedicated GND leads and must also be connected to the same ground plane. Reflow profile follows MSL1: peak temperature ≤235°C (HMC400MS8) or ≤260°C (HMC400MS8E).
Is the HMC400MS8TR pin-compatible with the HMC400MS8E variant?
Yes, HMC400MS8TR and HMC400MS8E share identical pinout, package dimensions, and electrical specifications. The sole difference is RoHS compliance: HMC400MS8E uses 100% matte tin lead finish and supports higher reflow temperatures (260°C), while HMC400MS8 uses Sn/Pb and max 235°C. Both are drop-in replacements in layout and circuit design.
