Product details
Overview
HMC527LC4 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q mixer operating from 8.5–13.5 GHz RF/LO and DC–2 GHz IF, delivering 9.5 dB typical conversion loss, 25 dB typical image rejection, and +28 dBm input IP3 - enabling high-linearity downconversion in microwave point-to-point radios.
For engineers reviewing the HMC527LC4 datasheet, HMC527LC4 pinout, HMC527LC4 application, or HMC527LC4 equivalent, this page provides verified RF performance data, validated 24-lead 4×4 mm SMT package mapping, thermal limits, absolute maximum ratings, and confirmed alternatives for image-reject mixer selection in E-band wireless infrastructure.
Technical Context
The HMC527LC4 integrates two double-balanced GaAs MESFET mixer cells with an on-die 90° hybrid to generate quadrature IF outputs without external hybrids. It operates as either an Image Reject Mixer (IRM) or Single Sideband Upconverter, with RF and LO ports AC-coupled and matched to 50 Ω across 8.5–13.5 GHz.
Its DC–2 GHz IF bandwidth supports baseband and low-IF architectures; amplitude balance is ±0.4 dB and phase balance ±6° over frequency and temperature. LO drive sensitivity is optimized at +19 dBm, with 45 dB LO-to-RF isolation and 24 dB LO-to-IF isolation under nominal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 8.5–13.5 GHz - full-band operation without tuning; usable as IRM or SSB upconverter in X/Ku-band systems. |
| IF Frequency Range | DC–2 GHz - supports zero-IF and low-IF receivers; requires DC blocking only if DC operation not needed. |
| Conversion Loss (Typ.) | 9.5 dB - measured at TA = +25°C, IF = 100 MHz, LO = +19 dBm; defines signal path attenuation in receiver chains. |
| Image Rejection (Typ.) | 25 dB - enables >60 dB adjacent channel suppression in heterodyne architectures without external filtering. |
| Input IP3 (Typ.) | +28 dBm - ensures robust two-tone linearity in dense RF environments such as VSAT terminals and military comms. |
| LO to RF Isolation | 45 dB - minimizes LO leakage into antenna paths, reducing spurious emissions and easing front-end filter requirements. |
| Operating Temperature | −40°C to +85°C - qualified for outdoor wireless infrastructure and ruggedized military platforms. |
Pinout & Package
24-lead leadless RoHS-compliant SMT package (4×4 mm, 16 mm²), alumina body with gold-over-nickel plating, MSL3 rating, and exposed ground paddle requiring soldering to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6–8, 10, 13, 17–24 | No Connect (NC) | Internally unconnected; may be tied to RF ground without performance impact. |
| 3, 5, 12, 14, 16 | Ground | RF/DC ground reference; must connect to PCB ground plane with low-inductance vias. |
| 4 | RF Input | AC-coupled, 50 Ω matched port for 8.5–13.5 GHz RF signal; no external matching required. |
| 9 | IF1 Output | DC-coupled I-channel output; max ±3 mA DC current; requires external DC block for AC-only IF use. |
| 11 | IF2 Output | DC-coupled Q-channel output; identical electrical behavior to IF1; used with IF1 for quadrature demodulation. |
| 15 | LO Input | AC-coupled, 50 Ω matched port for 8.5–13.5 GHz local oscillator; +19 dBm nominal drive level. |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Front-end mixer in wideband tunable receiver with fast frequency agility and low spurious generation. Use Value: 45 dB LO-to-RF isolation prevents LO feedthrough during rapid channel switching, maintaining receiver sensitivity at −110 dBm. |
Use Scenario: Vector signal analyzers and microwave signal generators requiring calibrated I/Q modulation/demodulation. IC Role / Device Role / Timing Role: Reference-grade IRM in calibration loopback paths for amplitude/phase error correction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC8192LP5E | Wider RF range (6–24 GHz), higher conversion loss (11.5 dB typ.), same 24-lead 4×4 mm package. | Better suited for multi-band test equipment; less optimal for fixed 10–12 GHz radios due to higher loss. | Select HMC8192LP5E when broader frequency coverage outweighs 2 dB conversion loss penalty. |
| ADL5375-05 | Lower frequency (300 MHz–6 GHz), integrated LO buffer, +22 dBm IP3, different 24-lead 4×4 mm LFCSP package. | Targeted at sub-6 GHz cellular infrastructure; incompatible with Ku-band RF paths without external upconversion. | Choose ADL5375-05 only for LTE/5G FR1 transceivers; not a drop-in replacement for HMC527LC4's 8.5–13.5 GHz role. |
Compared with HMC8192LP5E and ADL5375-05, the HMC527LC4 delivers optimal trade-off of Ku-band coverage, 9.5 dB conversion loss, and 25 dB image rejection - making it the preferred choice for fixed-frequency, high-linearity microwave IRM applications where size and thermal efficiency are constrained.

FAQ
What is the recommended LO drive level for optimal performance of the HMC527LC4?
The HMC527LC4 achieves best image rejection and conversion loss at +19 dBm LO drive. At this level, typical image rejection reaches 25 dB and conversion loss is 9.5 dB. Lower drive (e.g., +17 dBm) degrades image rejection by ~3 dB; higher drive (+21 dBm) increases distortion risk without meaningful gain improvement. The HMC527LC4 datasheet specifies +19 dBm as the nominal condition for all key RF specs.
Can the HMC527LC4 operate as both an image-reject mixer and a single-sideband upconverter?
Yes, the HMC527LC4 supports dual-mode operation: as an image-reject downconverter (IRM) with RF input and I/Q IF outputs, and as a single-sideband upconverter with I/Q IF inputs and RF output. Its internal 90° hybrid and balanced topology enable both configurations without external component changes - confirmed in the functional diagram and application notes for HMC527LC4.
What are the absolute maximum ratings for RF/IF input and LO drive on the HMC527LC4?
The HMC527LC4 has an absolute maximum RF/IF input power of +20 dBm and LO drive of +27 dBm. Exceeding these risks permanent damage. Continuous dissipation is rated at 460 mW at 85°C, derating 7.1 mW/°C above that temperature. Channel temperature must not exceed 150°C. These limits are specified in the Absolute Maximum Ratings table of the official HMC527LC4 datasheet.
Is DC coupling required on the IF1 and IF2 pins of the HMC527LC4?
IF1 and IF2 are DC-coupled outputs; DC operation is supported but requires limiting DC current to ±3 mA per pin to avoid non-function or failure. For AC-only IF use (e.g., bandpass IF filters), external series capacitors must be added. The HMC527LC4 datasheet explicitly states that exceeding ±3 mA DC current on IF1 or IF2 will cause part malfunction - a design constraint unique to this MMIC mixer.
Does the HMC527LC4 require external matching networks on RF or LO ports?
No. The HMC527LC4 features internal 50 Ω matching on both RF (Pin 4) and LO (Pin 15) ports across 8.5–13.5 GHz, eliminating need for external matching components. This is verified in the Pin Descriptions and Return Loss plots in the HMC527LC4 datasheet, which show < −10 dB return loss across the full band with no external tuning.
