Product details
Overview
HMC528LC4TR-R5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q mixer designed for RF front-end signal translation in 11–16 GHz systems. It functions as an image-reject mixer (IRM) or single-sideband upconverter with 35 dB image rejection, +26 dBm input IP3, and 10.5 dB typical conversion loss at +19 dBm LO drive - enabling high-linearity downconversion in point-to-point radios and test equipment.
For engineers reviewing the HMC528LC4TR-R5 datasheet, HMC528LC4TR-R5 pinout, HMC528LC4TR-R5 application, or HMC528LC4TR-R5 equivalent, this device supports DC–3.5 GHz IF bandwidth, requires no wire bonding, and integrates a monolithic 90° hybrid for quadrature IF generation - critical for SSB modulation, spectral purity, and compact SMT layout in microwave transceivers.
Technical Context
The HMC528LC4TR-R5 implements two double-balanced GaAs MESFET mixer cells with an on-die low-frequency quadrature hybrid to generate 100 MHz USB IF output. Its architecture enables intrinsic image rejection without external hybrids when used as an IRM.
It operates with AC-coupled 50 Ω RF and LO ports (11–16 GHz), DC-coupled IF1/IF2 ports, and requires all ground pins plus the exposed paddle to be soldered to PCB RF ground. Thermal resistance is 145 °C/W junction-to-die-bottom, supporting operation from –40 °C to +85 °C.

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 (10–20 GHz), higher LO drive (+23 dBm), but larger 5×5 mm package and no DC-coupled IF | Better suited for 18 GHz test equipment; less ideal for DC-coupled zero-IF receivers | Select if extended frequency coverage and higher LO power tolerance are prioritized over IF DC response and board space |
| Qorvo QM11024 | Similar 11–16 GHz range, but uses SiGe process; lower IP3 (+22 dBm), 20 dB image rejection, and no integrated hybrid | Requires external 90° hybrid; suitable for cost-sensitive, lower-performance military comms | Select if BOM cost reduction outweighs need for monolithic integration and high image rejection |
Compared with HMC528LC4TR-R5, the HMC8192LP5E offers broader bandwidth at the expense of IF DC coupling and footprint, while the QM11024 trades integration and linearity for lower cost and process maturity - making HMC528LC4TR-R5 optimal for size-constrained, high-fidelity microwave IRM designs.

FAQ
What is the recommended LO drive level for optimal performance of the HMC528LC4TR-R5?
The HMC528LC4TR-R5 achieves best-in-class image rejection and IP3 at +19 dBm LO drive. Performance remains stable between +17 dBm and +21 dBm, but below +17 dBm conversion loss increases and above +21 dBm risks compression. The datasheet specifies +19 dBm as the reference condition for all key specs including 35 dB image rejection and +26 dBm IP3 - so HMC528LC4TR-R5 should be biased at this level unless system-level trade-offs require adjustment.
Can the HMC528LC4TR-R5 operate with DC-coupled IF outputs in zero-IF receiver designs?
Yes - both IF1 and IF2 pins of the HMC528LC4TR-R5 are DC-coupled and support true baseband operation. However, each IF pin must not source or sink more than ±3 mA DC current to prevent malfunction or permanent damage. This makes HMC528LC4TR-R5 suitable for direct-conversion receivers, provided external baseband circuitry respects this current limit - a key differentiator from AC-coupled alternatives.
Does the HMC528LC4TR-R5 require external matching components at RF or LO ports?
No - the HMC528LC4TR-R5 features internally matched 50 Ω RF and LO ports across its full 11–16 GHz band, verified by S-parameter data in the datasheet. No external matching networks are needed for nominal operation, though system-level filtering (e.g., pre-LO filtering) may still be required depending on application EMI requirements. This simplifies layout and improves repeatability versus discrete-mixer solutions.
How is thermal management handled for the HMC528LC4TR-R5 in high-power applications?
The HMC528LC4TR-R5 has a thermal resistance of 145 °C/W (junction-to-die-bottom) and requires the exposed paddle and all designated ground pins (3, 5, 12, 14, 16) to be soldered directly to a low-impedance PCB ground plane with multiple thermal vias. At maximum dissipation (448 mW at 85 °C), proper grounding keeps junction temperature within the –40 °C to +85 °C operating range - critical for maintaining HMC528LC4TR-R5 conversion loss and IP3 stability.
Is the HMC528LC4TR-R5 pin-compatible with other Hittite I/Q mixers like the HMC527LC4?
No - the HMC528LC4TR-R5 is not pin-compatible with HMC527LC4. While both are 24-lead 4×4 mm packages, their pin functions differ: HMC528LC4TR-R5 assigns IF1 to pin 9 and IF2 to pin 11, whereas HMC527LC4 uses different pin allocations and lacks DC-coupled IF outputs. Layout reuse is not possible; HMC528LC4TR-R5 requires its own dedicated footprint per the official outline drawing.
