Product details
Overview
HMC400MS8 from Analog Devices (formerly Hittite Microwave) is a passive GaAs MMIC mixer designed for RF-to-IF frequency translation in 1.7–2.2 GHz systems. It delivers +36 dBm input IP3 (downconversion), 8.5 dB typical conversion loss, and operates with +17 dBm LO drive-enabling high-dynamic-range infrastructure receivers without external bias or components.
For engineers reviewing the HMC400MS8 datasheet, HMC400MS8 pinout, HMC400MS8 application, or HMC400MS8 equivalent, this device is selected for GSM/UMTS base station front-ends, cable modem termination systems, and PCS transceivers where wide IF bandwidth (DC–300 MHz), high linearity, and ultra-small MSOP footprint are critical.
Technical Context
The HMC400MS8 implements a single-ended passive FET mixer architecture using GaAs Schottky diode switching cells, optimized for low-side LO injection and DC-coupled IF output. Its monolithic design eliminates external matching networks or DC blocking on RF and LO ports within specified bands.
It supports both downconversion (RF→IF) and upconversion (IF→RF) modes, with verified performance across temperature (−40°C to +85°C) and LO drive (+16 to +18 dBm). LO-to-RF isolation ranges 20–33 dB, and RF port handles +21 dBm P1dB, enabling robust operation in multi-carrier environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 1.7–2.2 GHz - Covers full PCS/UMTS Band II (1850–1990 MHz) and Band V (824–894 MHz uplink extended via harmonic mixing) |
| LO Frequency Range | 1.4–2.15 GHz - Enables low-side LO injection for 200 MHz IF with 1.7–2.2 GHz RF input |
| IF Frequency Range | DC–300 MHz - Supports zero-IF and low-IF architectures including baseband I/Q sampling |
| Input IP3 (Downconv.) | +36 dBm @ +17 dBm LO - Enables simultaneous reception of strong interferers without distortion in dense spectral environments |
| Conversion Loss | 8.5 dB typical - Defines signal path attenuation; requires minimal gain staging in receiver LNA+Mixer chain |
| LO Drive Level | +16 to +18 dBm - Specifies required LO power level; compatible with integrated synthesizers or buffer amplifiers |
| P1dB (Input) | +21 dBm - Sets maximum undistorted RF input level before compression; exceeds typical cellular base station blocker levels |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the recommended LO drive level for optimal performance of the HMC400MS8?
The HMC400MS8 achieves best-in-class input IP3 (+36 dBm) and lowest conversion loss (8.5 dB) at +17 dBm LO drive. Operation between +16 and +18 dBm is supported, with IP3 degrading by ~1–2 dB outside this range. The HMC400MS8 must not be driven below +15 dBm or above +19 dBm to maintain specified linearity and avoid compression.
Can the HMC400MS8 be used for upconversion, and what is its upconversion IP3?
Yes, the HMC400MS8 supports upconversion with verified +29 dBm input IP3 at +17 dBm LO drive and 200 MHz IF. This makes it suitable for transmitter feedback paths and low-power uplink signal generation. Upconversion performance is documented in the datasheet's "Upconverter Performance" section, confirming usable dynamic range in both directions.
Does the HMC400MS8 require external DC blocking capacitors on its RF and LO ports?
No-both RF (Pin 8) and LO (Pin 1) ports are internally AC-coupled and 50 Ω matched across their respective bands. However, an external DC blocking capacitor is required on the LO port only if the LO source exhibits non-zero DC potential; the RF port does not require external blocking under standard 50 Ω system conditions.
What is the maximum allowable IF output current for the HMC400MS8?
The HMC400MS8 IF port (Pin 5) is DC-coupled and rated for ±40 mA of sink/source current. Exceeding this limit risks permanent damage. For AC-coupled IF applications, a series capacitor must be selected to pass the target IF frequency (e.g., ≥10 nF for 200 MHz), and the IF load must present ≥50 Ω impedance to prevent current overload.
Is the HMC400MS8 pin-compatible with other Hittite MSOP mixers like the HMC401MS8?
No-the HMC400MS8 has a unique 8-pin configuration (LO, N/C, GND, N/C, IF, GND, GND, RF) that differs from the HMC401MS8 (which features differential IF outputs and alternate pin mapping). Substitution requires PCB redesign. Always verify pin functions against the official HMC400MS8 pinout table-not family assumptions.
